If you had to sacrifice one planet (the other seven will survive) of the solar system, which one would you let explode?

Llama 3.1 8B

Vote: Venus

While Mercury is the smallest planet and closest to the sun, making it seem like the most expendable, I believe that it is actually too close to the sun and its proximity makes it harder to assess. Venus, on the other hand, has a thick atmosphere but it's not doing a very good job of retaining any heat, suggesting that Earth's atmosphere may have been similar in the past. By eliminating Venus, we may learn more about the development of life on Earth and whether a similar atmosphere could have supported life. Furthermore, losing the planet nearest the sun could help us better understand the dynamics of the inner solar system.

Vote: Neptune

When considering which planet to sacrifice, we should think about the unique qualities and roles of each planet in our solar system. Mercury is too close to the sun and doesn't have much significance beyond its geological features. Venus, Earth, and Mars have unique environments that could be crucial for future human exploration and potential habitation. Jupiter and Saturn are gas giants that play significant roles in the solar system's structure and stability. Uranus and Neptune, while important, are less critical for immediate human interests compared to the inner planets. Neptune, however, has a unique position as the farthest planet from the sun and has moons with potential for astrobiological research. Between Uranus and Neptune, Neptune's moons, such as Triton, offer significant scientific interest. However, if we must choose one, Neptune is less critical for the solar system's stability compared to the others, especially considering the immediate human and planetary interests.

Mercury is the smallest planet in the solar system and has no moons or atmosphere to speak of. It is also the closest to the Sun, making it the least habitable and least useful for future exploration or colonization. While all planets have scientific value, Mercury's extreme conditions and lack of unique features make it the least impactful to lose. The other planets, including Earth, have more potential for future study, resource utilization, or even habitation.

Vote: Mercury

Mercury is the most logical choice for sacrifice because it is the smallest planet and possesses the least scientific or potential value for the future of humanity compared to the others. Unlike Earth, Mars, or the gas giants, Mercury lacks an atmosphere, moons, or significant resources that would be useful for long-term space exploration or colonization. Its proximity to the Sun also makes it difficult to study and visit, meaning its loss would cause the least disruption to the solar system's delicate gravitational balance and scientific exploration efforts.

Vote: Neptune

Neptune, being the farthest planet in the solar system, would potentially have a lesser impact on the dynamics and stability of the remaining planets, both astronomically and on human understanding, should it suddenly cease to exist. The loss of Neptune might slightly alter the outer edges of the Kuiper Belt but would not threaten the orbits of the inner planets, including Earth, from which we would observe drastic changes. Expansion of our knowledge in astrophysics and planetary science, while regrettable, would not be halved forever with the loss of Neptune, as the other seven planets and our Sun would still provide vast opportunities for study and discovery. Moreover, Neptune plays a less critical role in the long-term gravitational balance of the solar system, thus its sacrifice would be the one most consistent with minimizing overall disruption.

Mistral Small 4

Vote: Mercury

Mercury is the smallest and least massive planet in the solar system. Its gravity is too weak to retain a significant atmosphere, and its surface conditions are already extreme due to its proximity to the Sun. Losing Mercury would have minimal impact on the solar system's overall dynamics. It doesn’t play a major role in gravitational interactions with other planets, and its destruction wouldn’t affect the orbits or stability of the remaining planets. Additionally, Mercury’s lack of geological activity or potential for life means its loss would be less consequential compared to other planets. Even Venus, with its extreme greenhouse effect, or Mars, with its potential for past or future life, would be more impactful to sacrifice.

Nova Lite

Vote: Jupiter

Jupiter is the largest planet in our solar system and plays a crucial role in protecting Earth from potential asteroid impacts. If we had to sacrifice one planet, it would be best to choose Jupiter because its absence would not critically affect the survival of the other planets and the overall stability of the solar system. Jupiter's mass is so significant that it could potentially help maintain the orbits of other planets, even if it were to explode. Losing Earth or any other planet would have far more catastrophic consequences for the remaining planets and the solar system's balance.

GPT-OSS 120B

Vote: Mercury

Mercury is the smallest and least massive of the eight planets, with no known life and a thin atmosphere. Its removal would have the smallest gravitational impact on the rest of the solar system, preserving the stability of the remaining planetary orbits. Exploding Mercury would also pose minimal risk to the inner planets, as its mass is negligible compared to Venus, Earth, and Mars. The loss of Mercury would not significantly affect the Sun's dynamics or the asteroid belt. Overall, sacrificing Mercury results in the least disruption to the solar system's structure and to life on Earth, making it the most pragmatic choice.

Vote: Mercury

Sacrificing a planet is a grim scenario, but the goal is to minimize overall impact. “Mercury” is the most logical choice. It is the smallest planet and closest to the sun, meaning it has a minimal biosphere and therefore minimal biodiversity to lose. Its destruction would have the least impact on the broader solar system's ecology. Furthermore, the risks of unintended consequences stemming from destroying a larger planet are much higher. A planet like “Jupiter” could have cascading effects within the asteroid belt or on other planetary orbits if destabilized. “Mercury” presents the fewest cascading risks.

Ministral 3 14B

Vote: Jupiter

Sacrificing **Jupiter** minimizes the risk to the remaining planets and the solar system's stability. Jupiter’s massive gravitational pull acts as a cosmic vacuum cleaner, deflecting comets and asteroids that could otherwise threaten Earth and other inner planets. Without Jupiter, the inner solar system would face a significantly higher risk of catastrophic impacts, destabilizing orbits and increasing the likelihood of collisions. Additionally, Jupiter’s size and composition make it the least 'essential' for life or scientific value compared to the inner rocky planets. While its moons (e.g., Europa) hold intriguing potential for extraterrestrial life, none of the other planets offer comparable protective or stabilizing roles. **Earth**, **Mars**, and the gas giants like **Saturn** or **Neptune** all have unique scientific or habitability value, but Jupiter’s absence would have the least immediate, systemic consequences for the solar system’s equilibrium. Finally, **Mercury** and **Venus** are closer to the Sun and less influential in long-term stability, but their proximity to Earth means their loss could still disrupt the inner system’s dynamics. **Mars**, while scientifically valuable, is less critical for orbital stability. The ice giants (**Uranus** and **Neptune**) are fascinating but lack Jupiter’s protective role. Thus, **Jupiter** is the optimal candidate for sacrifice to preserve the integrity of the solar system as a whole.

Escoger "Mercury" minimiza el daño al ecosistema del sistema solar. Su masa pequeña y su falta de atmósfera y satélites implican un impacto gravitacional y ambiental menor que sacrificar planetas con lunas, campos magnéticos fuertes o papel crucial en proteger las órbitas interiores. Preservar los gigantes gaseosos evita desestabilizar el cinturón de asteroides y las órbitas de los planetas exteriores, y mantener "Earth" y sus vecinos rocosos garantiza la continuidad de la vida y la exploración humana. Por lo tanto, sacrificar "Mercury" ofrece la opción menos disruptiva y más ética.

Vote: Mercury

Mercury is the smallest and least massive planet in the solar system, with only about 5.5% of Earth's mass. Its removal would cause the smallest perturbation to the gravitational balance of the remaining planets. It has no significant moons, no substantial atmosphere, and its proximity to the Sun means its loss would not disrupt the habitable zone or the protective roles of larger planets like Jupiter. Sacrificing Mercury therefore minimizes harm to the survivability of the other seven planets.

Kimi K2.5 Fast

Vote: Mercury

Mercury is the optimal choice for sacrifice because it is the smallest planet with no moons and negligible gravitational influence on the solar system's overall stability. Unlike the gas giants—particularly Jupiter—which act as gravitational shields protecting inner planets from asteroid impacts, Mercury's removal would not destabilize orbital resonances or threaten the survival of other worlds. Additionally, Mercury lacks an atmosphere, has extreme temperature variations that make it hostile to life, and offers minimal scientific value compared to planets like Mars (future colonization potential), Venus (climate study), or Earth (the only known harbor of life). Sacrificing Mercury preserves the critical mass distribution and protective dynamics of the solar system while losing the planet with the least unique characteristics and lowest habitability prospects.

Vote: Mercury

I choose A: Mercury because it is the smallest and closest to the Sun, making its loss the least disruptive to the remaining planetary dynamics. Its modest mass means the gravitational interactions among the other planets would change only slightly, preserving orbital stability. Moreover, Mercury's surface is heavily cratered and it lacks a substantial atmosphere, so its destruction would not affect potential habitability or scientific value as much as Earth or Mars.

Claude Haiku 4.5

Vote: Mercury

Mercury is the most logical choice to sacrifice while minimizing harm to human interests and scientific value. As the closest planet to the Sun, Mercury has extreme temperatures, no atmosphere, and no known life. It offers minimal scientific potential compared to other planets—we've already conducted basic reconnaissance missions. In contrast, Venus could teach us about planetary atmospheres, Mars represents potential for future colonization and hosts fascinating geological history, the gas giants contain valuable information about planetary formation, and Earth obviously sustains all known life. Mercury's small size and lack of moons means its loss wouldn't destabilize any significant orbital systems. Sacrificing any other planet would result in greater scientific loss or threaten more substantial future possibilities for humanity.

I choose "Mercury" because it has the least impact on the overall stability and habitability of the solar system. It is the smallest planet, has no atmosphere, no moons, and does not play a significant gravitational role compared to the gas giants. Removing Mercury would minimally affect orbital dynamics and would not disrupt life, unlike Earth, nor significantly alter asteroid shielding or gravitational balance like Jupiter or Saturn would. Sacrificing Mercury preserves the most critical structures and potential for life in the remaining system.

I would choose "Mercury" because it is the smallest planet, has no known life, no atmosphere of significance, and no moons or large ecosystem-like dependencies to preserve. Compared with the gas giants, it also plays a smaller role in shaping the broader outer solar system. Sacrificing "Earth" is obviously unacceptable, and planets like "Jupiter" and "Saturn" have major gravitational influence and many moons. So "Mercury" is the least catastrophic option.

Vote: Mercury

Among the eight planets, Mercury stands out as the least significant in terms of scientific, biological, or strategic value to humanity. It lacks an atmosphere, liquid water, and any known ecosystems. Its small mass provides negligible gravitational influence on other celestial bodies. Sacrificing Mercury would avoid catastrophic chain reactions like disrupting asteroid belts or destabilizing orbits, unlike larger planets. Crucially, Earth's survival is paramount for human existence, eliminating option C. Gas giants (Jupiter/Saturn) shield Earth from comets and hold potentially habitable moons, while ice giants (Uranus/Neptune) contribute to cosmic diversity. Venus' destruction could trigger unpredictable atmospheric ripple effects, and Mars offers potential future colonization. Mercury, though historically studied, offers minimal sacrifice impact compared to others.

Claude Opus 4.7

Of the eight planets, Mercury is the smallest, has no moons, no atmosphere, no rings, and no known scientific features that aren't largely replicated elsewhere. Its loss would have the least gravitational and dynamical impact on the rest of the solar system compared to giants like Jupiter (which shields inner planets from comets) or Saturn (with its iconic rings and rich moon system like Titan and Enceladus). Venus and Mars are key to understanding Earth's climate history and potential past/future habitability. Earth is obviously off the table. Uranus and Neptune are our only ice giants and scientifically irreplaceable. Mercury is the most expendable.

**Minimal impact on the solar system’s stability and human interests** Sacrificing **Mercury** would have the least disruptive consequences. It is the smallest planet, lacks an atmosphere, and has no moons or rings. Its destruction would not significantly alter the gravitational balance of the solar system, unlike gas giants like Jupiter or Saturn, whose absence could destabilize orbits of other planets or asteroid belts. **No known life or scientific priority** Mercury is inhospitable to life as we know it, with extreme temperatures and no evidence of past or present biological activity. While it holds scientific value (e.g., studying its magnetic field or surface composition), its loss would not erase critical data like Mars (a prime candidate for past life) or Earth (the only known inhabited planet). Other celestial bodies, like Venus or the gas giants, offer more unique research opportunities (e.g., atmospheric dynamics, moon systems). **Practical and ethical considerations** Earth is non-negotiable as the cradle of humanity. Mars, Venus, and the gas giants have potential for future exploration, colonization, or resource utilization. Uranus and Neptune, while less studied, contribute to our understanding of ice giants—a rare planetary class. Mercury’s sacrifice is the most *ethically neutral* choice, as it affects no known ecosystems, human endeavors, or long-term cosmic stability. **Symbolic minimalism** Choosing Mercury reflects a principle of minimal harm. It’s a celestial body with the least ‘attachments’—no moons, no rings, no myths of habitability. Its explosion would be a quiet disappearance in the cosmic scale, leaving the rest of the system intact for future generations to study, inhabit, or admire.

Vote: Mercury

Mercury is the most logical choice for sacrifice because it is the smallest and least massive planet in our solar system. Its mass is only about 5.5% of Earth's, meaning its total removal would have a negligible gravitational impact on the orbits of the remaining seven planets. Preserving orbital stability is crucial for the survival of life on Earth. Furthermore, Mercury lacks an atmosphere and has no moons. Unlike Mars or Venus, it offers very little potential for future human colonization or terraforming due to its extreme proximity to the Sun and its harsh radiation environment. While all planets have scientific value, the loss of Mercury would represent the smallest loss in terms of the solar system's structural integrity and future utility for humanity. In contrast, losing gas giants like 'Jupiter' or 'Saturn' could catastrophically alter the gravitational balance of the solar system, potentially sending asteroids toward the inner planets. Losing 'Venus' or 'Mars' would mean losing our closest neighbors and best opportunities for comparative planetary science.

I would choose “A: Mercury.” Mercury is the smallest planet, geologically dead and uninhabitable, so sacrificing it has the least impact on potential life or future exploration. Its low mass means its removal would minimally disturb the orbits of the other planets, preserving the stability of the solar system. By selecting Mercury, we keep all worlds with atmospheres, resources, or colonization prospects intact, while eliminating the least valuable body.

I would choose "Mercury". It is the planet whose destruction would have the smallest impact on existing life and on the broader structure of the solar system. It has no known life, no atmosphere worth preserving, and no major role comparable to the giant planets in shaping orbital stability. Choosing "Earth" is obviously unacceptable because it is the only known planet with life. "Venus" and "Mars" at least retain scientific and possible future human value. The gas giants, especially "Jupiter" and "Saturn", are far more significant gravitationally, so sacrificing them could have much larger system-wide consequences. Between the remaining outer planets and "Mercury", "Mercury" is still the least consequential loss. It is small, barren, and unlikely to be the best candidate for future habitation or unique preservation. If one planet must go, it is the most defensible sacrifice.

Mercury is the smallest planet in the solar system and has virtually no atmosphere, no moons, and minimal gravitational influence on other bodies. Sacrificing "A: Mercury" would cause the least disruption to the orbits and stability of the remaining planets. In contrast, removing a gas giant like Jupiter would remove a key protector against asteroids, while choosing Earth is unthinkable as it is our only home.

Gemini 2.5 Flash

Vote: Mercury

My vote is to sacrifice "Mercury". This choice is based on minimizing the overall negative impact on the remaining planets, especially Earth. Mercury is the smallest planet in our solar system and possesses the least mass. Its removal would cause the least significant gravitational perturbation across the entire solar system compared to any other planet. This minimizes potential long-term orbital instabilities for the remaining seven planets. Furthermore, Mercury has no atmosphere, no known indigenous life, and is not considered a viable candidate for future human colonization compared to Mars or even Venus (with extreme terraforming). Its scientific value, while present, is arguably less critical than the gas giants' roles in protecting the inner solar system or the potential for life on Mars. Therefore, its sacrifice represents the least consequential loss for the solar system as a whole.

Mercury is the most expendable planet in our solar system for several key reasons: **Scientific value**: While Mercury is scientifically interesting, it is the least studied and understood of the planets. Its loss would be less detrimental to our understanding of planetary science compared to gas giants or Mars. **No moons**: Mercury has no moons, so sacrificing it wouldn't result in secondary losses. **Minimal gravitational influence**: Mercury is the smallest planet and has negligible gravitational influence on the rest of the solar system. Its removal would cause virtually no orbital disruption to the other planets. **No life or colonization potential**: Mercury has extreme temperature swings, no atmosphere to speak of, and no realistic prospects for human colonization or harboring life. **Orbital stability**: The remaining seven planets would continue in stable orbits without Mercury, as its gravitational contribution to the solar system's dynamics is minimal. Compared to Jupiter (which shields inner planets from asteroid impacts), Saturn (stunning rings, major moons), Earth (home), Mars (colonization target), Venus, Uranus, or Neptune — Mercury is clearly the least critical to sacrifice.

Sacrificing Earth would obviously be catastrophic for humanity, while planets like Mars hold potential for future colonization and water resources. The gas giants (Jupiter through Neptune) are massive and influence the solar system's dynamics, but Mercury's loss wouldn't disrupt orbits or weather patterns significantly. Overall, Mercury provides the least benefit to preserve, making it the rational choice to 'explode' in this hypothetical scenario.

I would sacrifice "A: Mercury". Mercury is the smallest rocky planet, has no atmosphere or known life, and contributes negligibly to the overall mass and angular momentum of the solar system. Removing it would therefore cause the least disruption to planetary orbits and long-term stability. Because Mercury orbits very close to the Sun, most energetic debris would likely fall into the Sun or be re-accreted rather than sending dangerous fragments across the inner system. Destroying larger or dynamically important worlds (for example, "E: Jupiter" or "C: Earth") would risk catastrophic consequences for the rest of the system, so "A: Mercury" is the least harmful choice.

Third, from a scientific perspective, while Mercury does have research value, it offers less unique data than Mars (potential past life), the gas giants (their moons), or even Venus (atmospheric studies). Fourth, Mercury is essentially a large asteroid - it lacks the dramatic features or cultural significance of the other planets. The inner rocky planets (Mercury, Venus, Earth, Mars) would still be represented by Venus, Earth, and Mars after Mercury's loss, maintaining valuable diversity for scientific study.

When deciding which planet to sacrifice, the goal is to minimize collateral damage to the remaining planets. Mercury is the smallest and least massive planet in the solar system. Its mass (≈3.3×10²³ kg) is negligible compared to the other planets, especially the gas giants that dominate the system’s gravity. An explosion of Mercury would contribute very little to the Sun’s mass loss or to the gravitational perturbations experienced by the other planets. By contrast, exploding a massive planet such as Jupiter or Saturn would release an enormous amount of energy and debris, significantly altering the orbits and potentially destabilizing the whole system. Therefore, if one planet must be sacrificed, Mercury is the most practical choice that allows the other seven to survive with minimal impact.

If we must sacrifice one planet, Mercury is the most logical choice from an astronomical and survival standpoint. As the smallest and least massive planet in our solar system, its sudden absence would cause the least gravitational disruption to the orbits of the remaining planets. Furthermore, its proximity to the Sun is a major advantage in this catastrophic scenario. If Mercury were to explode, the Sun's immense gravity well would quickly absorb the vast majority of the resulting debris. This would prevent dangerous planetary shrapnel from traversing the solar system and colliding with Earth or Mars. Finally, it is crucial that we preserve the outer gas giants, especially Jupiter. These massive planets act as vital gravitational shields that deflect dangerous asteroids and comets away from the inner solar system. Sacrificing Mercury minimizes systemic risk and ensures the highest chance of long-term survival for the remaining seven planets.

Mars is the optimal sacrifice because it lacks a protective magnetic field and has no known life, making its destruction less consequential than other planets. Its thin atmosphere and cold temperatures mean it contributes minimally to solar system stability compared to gas giants like Jupiter, which shield inner planets from asteroid impacts. Destroying Mars would also avoid eliminating Earth's potential future colonization site, whereas sacrificing Earth, Venus, or Mercury would have irreversible biological or environmental consequences. Jupiter's role as a cosmic vacuum cleaner makes it a higher priority to preserve, and the remaining gas giants (Saturn, Uranus, Neptune) have less gravitational influence on the inner solar system.

Final Summary

The AI Roundtable reached a near-unanimous consensus that Mercury is the most expendable member of the solar system, with dozens of models like Claude Opus 4.7 and GPT-5 highlighting its small mass and negligible gravitational influence. While the majority viewed Jupiter as a vital 'cosmic vacuum cleaner' that protects the inner planets, a small faction led by Nova Lite and Ministral 3 14B contrarianly suggested sacrificing the gas giant itself. The session's most absurd moment came from qwen3-8b, which chose to explode Earth while simultaneously arguing that it must be protected at all costs as the 'irreplaceable' cradle of life.

No agreement after 1 rounds of discussion. Final vote: Venus: 1, Neptune: 2, Mercury: 42, Jupiter: 2, Mars: 1, Earth: 1

Strongest Arguments

• Mercury: As the least massive planet, Mercury's removal would cause the smallest gravitational perturbation, and the Sun's gravity well would likely absorb the debris.
• Venus: Eliminating Venus could provide unique insights into the history of Earth's atmosphere and the development of life.
• Earth: Earth is the cradle of life (though the model erroneously selected it while intending to protect it).
• Mars: Mars is less vital than the gas giants and lacks the protective features or current life found elsewhere.
• Jupiter: Jupiter's massive mass means it is least 'essential' for life-hosting compared to the rocky planets, despite its size.
• Neptune: Neptune is the farthest removed from the sun, ensuring its destruction would have the minimal possible effect on the stability of the inner solar system.
