How Long Could You Survive on Other Planets?

How Long Could You Survive on Other Planets?


As far as we know, Earth is the only place
in our solar system where humans can survive without a spacesuit. So if we ventured outside the cushy confines
of our home, how long would we live on the other planets? Mercury, the closest planet to the Sun, is
actually not the hottest of the bunch, but it does have the most extreme variation of
temperatures. Scientists once believed Mercury was tidally
locked – meaning only one side of the planet faced the Sun which explains why one side
is so hot while the other is so cold. But Mercury does rotate, just incredibly slow. At its current rotational velocity, it takes
about 176 Earth days to experience one Mercurian day-night cycle. But you wouldn’t make it to the next day
because you would die in about two minutes due to freezing or burning up. Mercury’s neighbor, Venus, is often thought
of as Earth’s twin sister because of the planets’ similar size and composition. But, the grass isn’t greener on the other
side because well there is no grass at all. The planet’s atmosphere, composed mainly
of thick carbon dioxide, traps the Sun’s heat causing scorching surface temperatures
higher than 470 degrees Celsius. The excess amount of CO2 molecules scatter
the Sun’s light, staining the sky a reddish orange. You better take in that unusual view real
fast because it’s the last thing you’ll see since Venus will vaporize you in less
than one second. Mars is the hottest contender for humanity’s
future home, and living there will literally take your breath away. Despite its flaming red color, Mars is not
hot. The average annual temperature is minus 60
degrees celsius with a low of minus 153 degrees. The Red Planet’s barely there air will have
you begging for a breath, and silicate dust will begin to cloud your lungs. Within about two minutes Mars’s low atmospheric
pressure will cause your organs to rupture resulting in a quick but painful death. Jupiter is nice to look at but if you touch
it, you’ll die. As far as we know, the gas giant has no surface,
so your body will descend through cloud-like layers of mostly hydrogen and helium. As you fall deeper, temperature and pressure
will rise. But you won’t feel anything because the pressure killed you less than one second after arriving on the planet. Saturn is another work of universal art. Driving across those rings would be like Rainbow
Road in real life. Except not at all because Saturn’s rings
aren’t solid. They’re made up of billions of particles
that range in size and are almost entirely water ice. And you likely won’t find solid ground on
the planet itself. Like Jupiter, the gassy composition of Saturn
would swallow your lifeless body faster than the tick of a clock. Uranus and Neptune don’t offer any hope
of survival either. And you’d likely die of boredom on the way there, considering the billions of kilometers of travel anyway. The ice giants are made up of mostly swirling
fluids, but they get their blue hues from methane gas in their atmospheres, which would cause you to suffocate. On top of the toxic gas, the extreme temperatures
on both planets would contribute to a nearly instant death. We are pretty lucky to live on Earth. Our planet’s proximity to the Sun enables
water to exist in liquid form, regulates temperatures and provides energy for photosynthesis. Earth’s atmosphere has a perfect mix of
gases that allow us to breath and the planet’s relatively stable magnetic field keeps solar
storms from frying us to a crisp. So, be thankful for our planet and treat her
well, because no one wants to spend their entire life in a spacesuit. Space Crafts takes you through the depths
of the cosmos, explaining bizarre astronomical phenomena and crazy plans for future exploration. Check out other episodes like this one about

  1. Should also discuss Saturn's moon Titan, even though it's not a planet. It's one of the least hostile places in the solar system.

  2. If we burn a matchstick, or simply make a spark or some sort of fire, will the entire atmosphere(or atleast the methane part of it) of Neptune and Uranus burn away?

  3. I just couldn’t overlook how all the planets are depicted as rocky and the suns light was in the wrong half of some planets.

  4. Isn't it titan that a person could survive with just a mask feeding them oxygen?

    I may be wrong on which moon but I know I've heard that one of them is warm enough and with enough atmosphere (just not oxygen) and everything that a person could survive without any protective suit.

  5. The intense field of radiation around Jupiter would probably kill you long before you get anywhere near its clouds.

  6. Question:
    Considering that the many planets have flamboyant gases. What would happen if we ignited?
    Are they burn off very quickly?
    Are they would explode?
    Are they become another "sun"?

  7. Great video but a better name for it would be, “How could the planets in our solar system kill you” or something like that cause you didn’t really do any analysis of how long we could actually survive in different scenarios. You just keep saying well die quick.

  8. We're not really "lucky" to live on Earth. We live on Earth because Earth is the only place around here to support life, or at least large complex life. Also we are adapted to Earth's conditions. It's not like humans were going to pop up anywhere and it was on Earth by chance.

  9. Ok this channel uploaded a video called “we may have just discovered the secret to life” that was mysteriously removed from their channel just 4 hours after release. I have a video on my channel for proof. However, when uploading the audio of my voice explaining things is gone… something odd is going on

  10. And science says everything started from nothing ….. and I say this just didn’t happened. Someone made sure we live her . God

  11. You only talked about the temperature that would kill you on Mercury. But other than the other planets it has a hot AND a cold zone. So somewhere in between has to be a zone where you would find a comfortable room temperature.
    So what about the atmosphere? You probably can't breathe it. But how thick is the atmosphere? How high is the pressure? Could you survive in those zones with room temperature just with a breathing mask like in Avatar?

  12. The easiest way to think about it is there is only 1 known planet in the entire universe where you wouldn't die almost instantly. And even if we find a perfect earthlike planet you'd die thousands of years before you got there.

  13. A lot of people are profiteering the misguided concept of colonizing other bodies in space. While we are being entertained by these 'scientists' and all of their plans and preaching of the dire consequences of remaining Earthbound, there is no reason to believe that humanity will not live and die on this planet just like ameba do in a pool of water. How soon humans become extinct depends on their cultural advancement.

  14. You wouldn't be vaporized visiting Venus. Well assuming you teleported to the surface.
    The gas giant's do have solid cores. I mean seriously do you think all that fallen debris just floats around aimlessly in the gas atmosphere? Anyway assuming you teleported to a equivalent depth proportionate to where the surface of our earth would be in relation to its total diameter your lifeless husk would fall at increasing speeds eventually vaporizing before you reach the core… So that was pretty on point. You'd be dead with in seconds on most planets even if you could just teleport to the surface. Thanks to the extreme cold and the existence of an atmosphere that conducts it… You'd also die of hypothermia before your organs could even rupture. I find it difficult to believe that organs such as your kidneys would rupture before death via asphyxiation could take place due to what we know about accidents taking place insise a vacuum… Oh and the fact that Mars' atmosphere is toxic due to perchlorates in the soil that also get kicked up and blown around…
    So yeah you're wrong about a lot of this.

  15. I'm still wondering why so many people are obsessed with the idea of going to live on Mars…It will be no better than living on the moon – in a tin can for the rest of your alien life.

  16. Ummmmm on the earth part were not actually safe on earth because all people are killing each other EVERONE is getting hurt almost everyday so you should cut that safe part out of earth a little but it’s a lovely place to live on though

  17. great video … it is not coincidence .. God/creator of the universe prepare Earth so well/complete facilities water,land,air,oxygen,mountains, river,animals,fish to live All Human beings here …. look around closest planet there is NO HOPE we will die instant just matter of second/minutes …. and we need to be thankful to the creator Alhamdulillah

  18. Humans are eventually live on space colony's and harvest minerals from every inch solar system, one day only rich and important people (like royal family) live on earth,
    You can make prediction what in future common humans live on space, rich people live on earth

  19. Nice vid, well written. I missed one fact tho. When u mention 'how lucky we are to be on earth … protected from the sun by its mag. field…' also the solar system's the location in the milky way is worth mentioning, i.e. 'quiet' spot.

  20. Am I the only one who thinks there could be life on planets such as Mercury or Venus or even Pluto. Hell for all we know there could even be life on the Sun. Who says it has to be human life, other species could adapt to survive on planets, suns and satellites that we could not survive on
