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

Elon Musk sent the first astronauts on the ISS and soon threatens to conquer Mars on the now under construction Starship. 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. How many people can live on different planets or even stars, in detail told Astrophysicist Neil DeGrasse Tyson in an interview with Business Insider. Now, when interest in the topic of space is especially high, it's time to remember this interview.

The sun

Obviously, the Sun will simply burn you instantly, because the temperatureSun Fact Sheet its surface 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

Into the Sunthat if you teleport to the Sun for one nanosecond (billionth of a second), and then return you back, then 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 lasts 88. The planet has practically no atmosphere, so the sky is always black there, and the Sun looks two and a half times larger than we see it from Earth, and it moves very strangely across the skyHow Long is Day on Mercury?
. The daytime side of Mercury is glowingHow Hot is Mercury? under +427 ° C, and at night it is cooled to −180 ° C.

But if you find yourself somewhere on the border between them (the so-called terminatorTerminator), you may well be able to surviveNeil deGrasse Tyson: Here’s How Long You Could Survive On Every Planet In Our Solar System - 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 loseLibrary of Past Questions, THE HUMAN BODY IN SPACE: DISTINGUISHING FACT FROM FICTION 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.What Would It Be Like to Live on Venus? from 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 is heating upLiving on Planet Venus: Why It Would Be Hard (Infographic) planet to +465 ° C, which causes constant rains from sulfuric acid, which at the surface turn into mists... also from sulfuric acid.

So, finding yourself on Venusyou will be crushed immediatelyNeil deGrasse Tyson: Here’s How Long You Could Survive On Every Planet In Our Solar System atmosphere and burned by heat and sulfuric acid.

Average Life Time: less than 1 second.

Earth

Mostly harmless.

Lifetime: from several seconds or minutes (if you find yourself next to aggressive predators, hostile people, over the oceans, in the crater of a volcano or in the highlands in a rarefied atmosphere) up to 122 years (official recordZhanna Kalman longevity, staged by the Frenchwoman Jeanne Kalman).

Mars

On Mars quite cold - from -60 to +20 ° C, but at the same time a very rarefied atmosphereWhat Would It Be Like to Live on Mars?, Atmosphere of Marscomposed 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 lastNeil deGrasse Tyson: Here’s How Long You Could Survive On Every Planet In Our Solar System without oxygen. If you have the foresight to bring an air cylinder with you, then you will be killedBoiling Blood and Radiation: 5 Ways Mars Can Kill 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).

Average Life Time: 2 minutes.

Jupiter

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

If you survived this and got to the upper layers of the atmosphere, then you will sweepWhat would happen if humans tried to land on Jupiter through them at a speed of 180,000 km / h (since Jupiter's gravity is much stronger than Earth's, you will fall faster). At about 250 kilometers, you will reach the 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 this does not matter to you, then after 12 hours of continuous fall you will find yourselfWhat would happen if humans tried to land on Jupiter 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 at the surface of the sun. No terminator will be saved here.

Average Life Time: less than 1 second.

Saturn

Everything said for Jupiter is trueNeil deGrasse Tyson: Here’s How Long You Could Survive On Every Planet In Our Solar System and for other gas giants. Saturn is no exception, and if you fall into its atmosphere, you will be crushed by monstrous pressure and destroyed by the high temperature.

Average Life Time: less than 1 second.

Uranus

Another gas giant. Pressure, temperature and radiation appliedNeil deGrasse Tyson: Here’s How Long You Could Survive On Every Planet In Our Solar System.

Average Life Time: less than 1 second.

Neptune

Despite the fact that Neptune is called an ice giant, in the depths of its hydrogen-methane atmosphere, the temperature reachesWhat Is The Surface of Neptune Like? 476.85 ° C. And the pressure is very high there. So what will happen to you on this planetNeil deGrasse Tyson: Here’s How Long You Could Survive On Every Planet In Our Solar System the same as on Jupiter.

Average Life Time: less than 1 second.
