What will happen to your body on different objects in the solar system

About the rains of sulfuric acid on Venus, hurricanes in the hydrogen atmosphere of Jupiter and other conditions that await you on different planets.

Elon Musk sent the first astronauts to the ISS and soon threatens to conquer Mars on the Starship under construction now. It is quite possible that the first flight to the Red Planet will happen in the next few years.

However, it will not be easy to colonize other celestial bodies, as Elon dreams, because the conditions on them, to put it mildly, are not the most comfortable. Astrophysicist Neil DeGrasse Tyson talks to Business Insider reporters about how many people can live on different planets or even stars. Now, when interest in the topic of space is especially high, it's time to remember this interview.

The sun

Obviously, the Sun will just instantly burn you, because its surface temperature is 5,499 ° C. In general, the Sun, naturally, has no surface - this is the name of the part between the core and the corona. You just disappear there without a trace.

But instantly - a loose concept. Physicist Randall Munroe, a former NASA employee, believes that if you teleport to the Sun for one nanosecond (a billionth of a second) and then return you back, you will survive. Your skin will receive five orders of magnitude less heat than a second touch of a butane burner, that is, you won't even notice anything.

But if you teleport a little closer to the core, where the temperature reaches 14,999,727 ° C, you evaporate in one femtosecond (one millionth of a nanosecond, or one quadrillionth of a second).

Average Life Time: 10⁻¹⁵ seconds.

Mercury

A day on Mercury lasts 59 Earth days, and a year - 88. The planet has practically no atmosphere, so the sky there is always black, and the Sun looks two and a half times larger than we see it from Earth, and it moves very much across the sky. strange

… The daytime side of Mercury heats up to +427 ° C, and the night side cools down to −180 ° C.

But if you find yourself somewhere on the border between them (the so-called terminator, you can easily survive - as long as you can do without oxygen.

There is almost a vacuum on the surface of Mercury, so your lungs, if air remains in them, are likely to burst, your body will begin to swell, and your blood will boil. In 10-15 seconds you will lose consciousness from lack of oxygen, and after 1-2 minutes you will die without regaining consciousness. Simple hypoxia will kill you.

Average Life Time: 2 minutes.

Venus

Venus has nearly the same gravity as Earth, but has a much denser atmosphere of carbon dioxide. The air is so thick that it is difficult to move in it - like in the Pacific Ocean at a depth of 914 meters. A day on Venus lasts 116 Earth days, but the atmosphere does not transmit sunlight well, and it is very dark on the surface.

The greenhouse effect heats the planet to +465 ° C, which causes constant rains from sulfuric acid, which turn into mists at the surface … also from sulfuric acid.

So, once on Venus, you will immediately be crushed by the atmosphere and burned by the heat and sulfuric acid.

Average Life Time: less than 1 second.

Earth

Mostly harmless.

Lifetime: from a few seconds or minutes (if you find yourself next to aggressive predators, hostile people, over the oceans, in a volcano crater or on high mountains in a rarefied atmosphere) to 122 years (the official record of longevity set by the Frenchwoman Jeanne Calment).

Mars

It is quite cold on Mars - from -60 to +20 ° C, but at the same time there is a very rarefied atmosphere, consisting mainly of carbon dioxide, as well as nitrogen and argon, so the low temperature will not be felt as much as on Earth. Naturally, there is nothing to breathe there.

You will live on Mars for as long as you can survive without oxygen. If you have prudently brought an air balloon with you, then low atmospheric pressure (in a few minutes), cold (in a few hours), Martian dust damaging the lungs (in a few weeks), or radiation (in a few months) will kill you.

Average Life Time: 2 minutes.

Jupiter

Jupiter is a gas giant and has no surface to land. If you fall on it from a great height, you will most likely be killed by very strong radiation even before approaching the planet's atmosphere.

If you survived this and got to the upper layers of the atmosphere, you will sweep through them at a speed of 180,000 km / h (since gravity on Jupiter is much stronger than Earth's, you will fall faster). At about 250 kilometers, you will reach ammonia clouds and experience a temperature of −150 ° C and strong winds - hurricanes in Jupiter's hydrogen atmosphere reach speeds of 482 km / h. The pressure is already enough to kill.

If you don't care about this, then after 12 hours of continuous fall you will find yourself in the lower layers of the atmosphere, where impenetrable darkness reigns, the pressure is 2,000,000 times higher than that of the Earth, and the temperature is higher than on the surface of the Sun. No terminator will be saved here.

Average Life Time: less than 1 second.

Saturn

Everything said for Jupiter is true for other gas giants as well. Saturn is no exception, and if you fall into its atmosphere, you will be crushed by monstrous pressure and destroyed by heat.

Average Life Time: less than 1 second.

Uranus

Another gas giant. Pressure, temperature and radiation are included.

Average Life Time: less than 1 second.

Neptune

Despite the fact that Neptune is called an ice giant, in the bowels of its hydrogen-methane atmosphere, the temperature reaches 476, 85 ° C. And the pressure is very high there. So on this planet the same thing will happen to you as on Jupiter.

Average Life Time: less than 1 second.
