How YOU'D Die on Every Solar System Planet

Added: 2026-05-25

[00:00:00]2 1 Have you ever watched a SpaceX launch and thought to yourself, "I could do that. I could manifest my destiny, hop on that interestingly shaped rocket, and live on another planet." Well, when you forget your phone charger and your day's ruined, now imagine forgetting oxygen.

[00:00:20]Because every planet out there has a very creative way of ending you, and some of them are honestly overachievers.

[00:00:30]Since I was a wee little bird nestled in my mother's arms, I've wondered what it was like to die on every planet. But, unlike you, I don't suffer the same limitations of a human body. Wow, I'm the first human on Mercury. This is really Wait, what?

[00:00:47]The sun-facing side of Mercury reaches approximately 430° C.

[00:00:52]That's hot enough to melt lead. That's also, coincidentally, hot enough to melt you. Though, you would technically vaporize before you got a chance to melt. Without a proper magnetic field, Mercury receives almost seven times more energy from the sun than Earth does. All of it arrives at the surface completely unfiltered, and right now, it's arriving on you. You'd absorb a lethal dose of radiation in hours, and your DNA would unravel faster than a Kardashian's marriage.

[00:01:19]Also, Mercury has a thin exosphere, rather than a true atmosphere. It's composed of bits of atoms blasted off the surface by solar wind. Due to that lack of atmospheric pressure, the boiling point of water is lower. This would cause your organs to fail as all your bodily fluids evaporate. Now, if we respawn you on the night side, you'd face -180° C.

[00:01:41]As soon as the sun sets, which takes a while since a single day-night cycle on Mercury lasts about 176 Earth days, the temperature would plummet. With no true atmosphere to hold the day's heat, the warmth escapes into space almost instantly. Your fingers and toes start to go numb and turn black as hypothermia kicks in. Instead of evaporating, your bodily fluids start to freeze and ice crystals start to form in your cells.

[00:02:05]The only place with any marginal survivability is the terminator zone, the narrow boundary between day and night where temperatures briefly stabilize. Though, since the planet is still slowly spinning, you would have to be constantly moving to not get dragged back to the dark side or the day side.

[00:02:21]But even in the terminator zone, the radiation is still intense and you'd still have that pesky no oxygen issue to deal with.

[00:02:28]Interesting. Two minutes on the day side, a slow agonizing freeze on the dark.

[00:02:37]Wait, huh? I'm alive. How am I alive?

[00:02:40]What are you?

[00:02:42]I need to turn on respond without memory next time. Obliviate.

[00:02:47]Wow, we're on Venus. This is really >> [cough] >> Venus has an atmosphere made primarily of carbon dioxide. The atmospheric pressure at the surface is 92 times that of Earth's, roughly equivalent to being 900 m underwater.

[00:03:04]Your body wouldn't so much explode as it would simply compress enthusiastically, all at once. Your lungs cannot expand against it. Suffocating from the lack of oxygen would become the least of your problems. You would be mechanically crushed by air before you had time to register the surface temperature. Which, by the way, is a constant cheerful 465° C, hotter than Mercury, maintained 24 hours a day by the most aggressive greenhouse effect in the solar system. Venus's thick carbon dioxide atmosphere traps heat so efficiently that the surface temperature never drops, never varies between day and night, and never changes between the equator and the poles, which means you're equally dead everywhere on its surface. The Soviet Venera 13 probe, one of the toughest machines humanity ever sent to a planetary surface, survived on Venus for a maximum of 127 minutes. Since you are not a Soviet probe, your suit would dissolve and you would dissolve. Instead of bright, white, fluffy clouds, the clouds above you are made of sulfuric acid. The rain is acid rain. Though it doesn't reach the surface, it evaporates back upward before landing. But it forms and falls and re-evaporates in a continuous cycle above your head because this planet is a big old FU to humanity.

[00:04:23]Now, this planet is familiar and homey.

[00:04:26]Though this doesn't look like the right time period.

[00:04:29]Oh, Eenie, meenie, that's a big guy.

[00:04:31]That's a really big guy.

[00:04:38]Mhm, still not right. Eenie, meenie, >> [screaming] >> there we go.

[00:04:44]>> [music] >> Well, sh Unlike every other planet on this list, Mars almost looks like it could work out in the same way you thought gas station sushi would work out. It has days that are 24 hours and 37 minutes long. That's close enough that your circadian rhythm would barely notice. It has seasons. It has ice caps. It once had liquid water.

[00:05:15]It has mountains and valleys and plains.

[00:05:17]During the daytime, it can get to a nice and comfortable 20° C.

[00:05:21]While standing on its surface, you might also think you were unfortunate enough to end up in Arizona. Emphasis on the almost.

[00:05:28]The atmosphere on Mars is 95% carbon dioxide and so thin it provides almost no protection from radiation, from meteorites, or from the cold. Surface pressure is less than 1% of Earth's, which means that without a pressurized suit, the gases in your blood would begin to bubble in a condition known as embolism. Your blood would boil. Your saliva would bubble on your tongue. Your tears would vaporize. Your skin would swell. You would lose consciousness in about 15 seconds and be dead in under 2 minutes. Wow, that was a graphic. Here, look at a video of puppies instead. Even with a perfectly pressurized space suit at night, the temperature plunges to -73° C and -128° C at the poles in winter. And then, there's the radiation. Without Earth's magnetosphere or thick atmosphere, Mars's surface receives relentless cosmic radiation and solar particle events. If you became a long-term resident, assuming you somehow survived everything else, you would face dramatically elevated cancer risk, neurological degradation, and genetic damage. Also, Martian dust storms can engulf the entire planet for months at a time, blocking sunlight, clocking equipment, and coating every surface in a fine, slightly toxic dust. You'd be trapped, powerless, and slowly freezing in the dark. Now, according to chapter 10, section 42 of this HR handbook, this next planet has no surface, so we can't just teleport there. Or was that the you can't go back in time and marry your mother section? Nonetheless, here is a conveniently placed spaceship for us to take.

[00:07:02]>> [music] >> First, you don't land on Jupiter, you enter it. Jupiter's magnetosphere is the strongest of any planet, with the magnetic field at the cloud tops being 20,000 times stronger than Earth's. The moment you entered its atmosphere, the radiation alone would be lethal.

[00:07:19]Jupiter's upper clouds are cold, around -145° C.

[00:07:24]Assuming you survived radiation and the cold, the gas becomes gradually denser the deeper you go.

[00:07:29]Due to the increased density, the pressure and temperature rise. By the time you reach the liquid metallic hydrogen layer deep inside Jupiter, pressure would be 3 million times Earth's atmospheric pressure. The core temperature is estimated at 24,000° C, roughly five times hotter than the surface of the sun.

[00:07:47]You and the ship would not just be crushed and incinerated, but would also be incorporated into the planet as your atoms are disassembled and distributed.

[00:07:55]And then there are the storms. Jupiter's Great Red Spot is a storm that's been raging for at least 190 years, possibly longer.

[00:08:03]It's wider than Earth and has winds of 432 km/h or 268 mph. It is, by any reasonable definition, the longest running disaster in the solar system.

[00:08:15]Also, there are smaller lightning storms on Jupiter. Smaller meaning the size of continents that form, merge, and occasionally consume each other in what scientists describe as chaotic vortex interactions, and what you would describe as approximately four words, all of them the same, and would probably get us demonetized. You'd be radiation cooked, then pressure compressed into your constituent atoms.

[00:08:39]>> [music] >> Now, here's a planet that would be great for your Instagram reels. Saturn has rings made of ice and rock extending 282,000 km from the planet's center. It's beautiful, magnificent, and an absolute zaddy. 10 out of 10 on the visuals.

[00:08:55]However, zero out of 10 for survival.

[00:08:58]Saturn is a gas giant. Like Jupiter, it has no surface. Also like Jupiter, the atmosphere begins cold and violent at the top and transitions through increasing pressure and heat until you stop being a coherent structure. Your demise is almost identical. The major difference is wind. Saturn's winds reach 1,800 km/h or 1,100 mph near the equator, which is among the fastest in the solar system. You are moving sideways at roughly the speed of a rifle round while simultaneously being compressed and heated from all sides.

[00:09:29]The upper atmosphere sits at At the poles, a hexagonal storm system hundreds of kilometers deep has been rotating for more than 40 years.

[00:09:39]Near the core, the temperature climbs to 11,700° C and the pressure exceeds 1,000 times Earth's atmosphere.

[00:09:47]One more thing worth noting, Saturn is less dense than water. If you had a bathtub large enough, Saturn would float in it.

[00:09:55]And this fact is completely useless to you as you're being destroyed by wind inside its atmosphere. But it is the kind of thing that felt important to share. Now, let's take a look at Uranus.

[00:10:08]Uranus is the coldest planet in the solar system. The upper atmosphere reaches -222° C, colder than Neptune, despite Neptune being farther from the sun. With it being 2.9 billion kilometers away from the sun, far less sunlight reaches Uranus, making it 400 times dimmer than Earth.

[00:10:27]Just like Jupiter and Saturn, Uranus has no surface, so you would keep descending towards the core. And the further you descend into Uranus, the darker it gets.

[00:10:36]Uranus is an ice giant, but it is not actually made of ice, but of water, methane, and ammonia in a hot, dense fluid state under crushing pressure wrapped in a hydrogen-helium atmosphere.

[00:10:47]Hydrogen sulfide in the atmosphere also makes Uranus smell like rotten eggs.

[00:10:52]Uranus orbits on its side at a 98° axial tilt, which means Uranus's poles experience 42 years of continuous sunlight followed by 42 years of darkness.

[00:11:03]If you arrive at Uranus's dark pole in winter, you experience perpetual darkness while the cold and toxic atmosphere of hydrogen, helium, and methane suffocates you. As this ship descends further into Uranus, the pressure climbs to 100 times Earth's atmosphere, and the temperature begins rising despite the cold exterior. Under those conditions, carbon atoms compress until they form diamonds. They fall toward the core in a constant rain. You and this ship would also compress under those conditions while being pelted by diamond rain. A spectacular way to go out, and I'm out of puns. So, let's get out of Uranus and head to Neptune.

[00:11:40]>> [music] >> Neptune is 4.5 billion kilometers from the Sun and receives 900 times less sunlight than Earth. Despite this, Neptune has the fastest winds in the solar system, 2,100 kilometers an hour, faster than the speed of sound in air, faster than any other planet.

[00:11:57]Neptune emits significantly more heat than it receives from the Sun, suggesting an active core driving its surface dynamics from below.

[00:12:05]You enter the upper atmosphere at -220° C.

[00:12:09]The wind at 2,100 kilometers an hour rips apart this [music] ship in every direction. You cannot maintain orientation. The ship becomes components before you've processed what's happening. As you fall deeper, the pressure and temperature build toward a layer of superionic water, a state of matter where oxygen atoms lock into a crystalline lattice while hydrogen ions flow freely through it, conducting electricity. Neither fully solid nor fully liquid, like Jupiter and Saturn, there is no surface. Just like on Uranus, the increased pressure causes it to rain diamonds. You keep going until you're frozen, shredded by supersonic winds, and buried in diamonds.

[00:12:48]Pluto, the first and only planet to get fired from the job. The journey to Pluto alone in a spaceship takes approximately 9 to 10 years. By the time you arrived, you would have aged a decade and experience significant muscle atrophy and bone density loss. But, since Pluto has a surface, we can just teleport there.

[00:13:09]At the outer edge of the solar system, Pluto's surface temperature is -230° C.

[00:13:15]It's so cold that nitrogen freezes solid and sits on the surface as ice. Its atmosphere is a thin haze of nitrogen and methane that freezes and falls as snow when Pluto moves farther from the Sun in its elliptical orbit. Exposed to Pluto's surface, you would freeze in seconds. Your body would become a statue. In the low gravity, about 6% of Earth's, you might have time in the two or three conscious seconds before hypothermia took hold to look up and see the Sun as the brightest star in an otherwise completely black sky.

[00:13:48]That was the most anticlimactic death in the solar system. You'd freeze. That's it. There's not even an interesting atmosphere to dissolve you. Radiation, heat, pressure, embolism, hypoxia, it seems Earth is currently the only planet humans can survive on. I wonder why.

[00:14:03]Anyway, check out this video.
