How long would a person live on Neptune?

Answer 1

That is actually a fascinating question.

It would be a race between which would kill you faster, the intense cold of negative 373 degrees Fahrenheit atmospheric temperature, or the poisonous atmosphere of hydrogen, helium and methane.

There is no solid surface, and no possible sources of food or potable water - but that's irrelevant, as you'd be dead before that could become an issue.

As liquid nitrogen is used to flash freeze organic food stuffs, and occurs virtually instantaneously, and as the freeze point of liquid nitrogen is negative 346 degrees, one can see that give Neptune's temperature, you would freeze solid before you could choke to death for lack of oxygen.

If you were very observant, you might notice in the second or two you'd have, that you were being buffeted by winds of around 1,200 miles per hour. I suppose this "wind chill" would make the negative 330 to 360 degrees feel colder, but I doubt you'd exist long enough to complain!

Assuming you were in a spacesuit, you'd still die. You'd have until you dropped through the atmosphere to the molten core comprised of rock, ammonia and methane. And as the gravity is 114% of Earths, drop you would. If you started at the top of the atmosphere, you would accelerate downward at approximately 36 feet per second per second, reaching a maximum velocity of approximately 137 miles per hour within 10 seconds.

As the atmosphere is about 4,350 miles deep, you'd have about 32 hours to be blown around before hitting that molten surface. Assuming you had 32 hours of air in your suit tanks, and assuming the winds and conditions didn't damage or destroy your suit.

There you have it. No suit, about 1 or 2 seconds. With a suit, possibly 32 hours, but probably not. The top of the atmosphere has unusually high temperatures of around 900 degrees, plummeting down to negative 373 degrees. This would have effects difficult for any of our standard protective suits to deal with, neverminding that there are bits of super heated debris blowing through the atmosphere at trans-sonic speeds!

Your best chance of survival is then to either not go there, or stay in the spaceship that took you there!

Answer 2

you cant if you try your an idiot so dont try actually do try and you will die

Answer 3

A person would not be able to live on Neptune as it is a gas giant with extreme cold temperatures and no solid surface to support human life.
