What You Would Look Like Living on 7 Different Planets

3 years ago

Stephen Hawking once said that we only have 100 more years before we move to space. That’s a rather tight deadline because — let’s admit it — we’d have some trouble surviving in space. Even astronauts, who only spend a few hours out there, often face health problems upon returning. Most of the planets in the universe are impossible for us earthlings to live on. In fact, we’d have to evolve ourselves, like with our vision, our breathing, and our vestibular system, almost entirely, to do it. But let’s give it a try.

We at Bright Side decided to lose our marbles for a bit and try to imagine how we’d look on different planets, and we want to share our speculations with you.

1. Mars

The gravity on Mars is lower than on Earth, and it’s farther from the sun, so we would see less sunlight. Mars also has no protective magnetic field due to its thin atmosphere, exposing everything to radiation. Sometimes, strong winds create dust storms that howl around the whole planet, and the dust continues to settle for months after.

  • Your look: You’d probably be tall with a robust build to compensate for poor gravity and would have bigger eyes to better perceive the far-off sun. To protect itself from radiation, your body would have to switch its pigmentation from melanin to carotenoids (which gives carrots, tomatoes, and oranges their color). So you’d probably have orange skin!

There’s no limit to our imagination, so we decided to create a more “human” form of the Martian appearance.

2. Jupiter

Living on the surface of Jupiter might prove to be challenging since there’s no actual surface. The planet consists entirely of gas. However, it doesn’t mean it’s just a giant cloud hanging in space — if you venture through its atmosphere to deeper parts, the gas becomes denser until it turns into liquid. So, one layer of Jupiter is an ocean made of hydrogen instead of water.

  • Your look: With high pressure, extreme temperatures, and a fluid environment, we’ll have to draw some inspiration from deep-water dwellers who deal with the same conditions but on a lesser scale. We’d be big isopods with shells to protect us from Jupiter’s radiation.

3. Saturn

Like its fellow gaseous neighbor, Jupiter, Saturn is a gargantuan cloud of hydrogen and helium with no solid land and powerful winds. Like Jupiter, it gets tighter within, but its core is much smaller. Its iconic rings are made of a myriad of ice particles, so nothing could live on them, unfortunately. Saturn’s average density is less than water, so this behemoth of a planet could float in a bathtub if there were one of a suitable size.

  • Your look: The only way to move within Saturn’s thick fog is by flopping around like a jellyfish. You’d have an umbrella-shaped bell to propel yourself up and no skeleton so that it wouldn’t be crushed by the pressure!

4. Mercury

Life is tough on Mercury. This tiny planet is the closest to the sun, so the sunlight here is 7 times bigger than on Earth — no sunscreen would be able to manage this. Mercury’s temperature is extreme, swinging between a scorching 800°F (430°C) during the day and −290°F (-180°C) at night. It’s all accompanied by constant meteorite rains and earthquakes. As a bonus, there is no atmosphere or air to breathe.

  • Your look: Flesh and bone could never handle these severe conditions. So, instead, people here would be made of something similar to refractory metal, like titanium. There’d be no need for a respiratory system, so your pretty metal face would be without a nose. And your eyes would probably look like thick sunglasses to protect them from all this sun exposure.

5. Venus

If there’s anywhere harder to live in than Mercury, it’s Venus. The temperature here is whopping 880°F (471°C), and the atmosphere is so thick, it creates a greenhouse effect. The surface is dry and full of surprises like volcanic eruptions, hurricane winds, and lightning. And as a cherry on the top, the pressure here feels like you’re 1 mile underwater, giving you a neverending headache.

  • Your look: Tragically, the only things that can possibly survive on Venus are microbes. Venus eats away at everything, even metal, making fast work of any human spacecraft. And Venus’ atmosphere contains phosphine, which is toxic for anything that breathes oxygen but means life for microbes.

6. Uranus and Neptune

Icy, dark, and plagued by strong winds, Uranus and Neptune are mostly made of cold liquids — methane, water, and ammonia. They don’t have a solid surface, and their atmospheres slowly merge into the water around the planets’ core. Gravity here is stronger than on Earth and applies more pressure on everything.

  • Your look: With a heavy gravitational pull, you’d be shorter and stockier, with a muscular body and thicker skin against the cold. And considering the fluid environment, your best bet is a cosmic whale or manatee, floating around the blue planets.

7. Pluto

The farthest planet-like object from the sun is appropriately freezingly cold and covered with ice, with weak gravity and a flimsy atmosphere. The sun, from Pluto, is nothing more than a dot on the horizon, much like the moon for Earth, so there’s not much going on in terms of light. However, scientists suggest that there may be a water ocean under Pluto’s surface and some nicer weather.

  • Your look: Let’s take notes from Earth’s creatures with built-in antifreeze, like some insects and fish. The low gravity makes the muscles and bones shrink and the space between vertebrae expand, making us taller. Your posture would also change since your spine, for the most part, would be out of a job. So you’d probably be tall, thin, and somewhat spider-like, with spindle limbs and a curved spine!

Why would you only have two toes per foot if you lived on Mars?


For defense I would choose mercury
But for swimming I would choose Uranus/Neptune and that one I prefer
