what happen if you were on the planet Neptune?

Answer 1

the news would have my face pasted all over it for being the first person to make it to neptune, then they'd call me crazy because if your on neptune,

YOUR DEAD.

actually neptunes gravity is very similar to earths. its below freezing cold, and no oxygen. (not too bad if your in a suit), but yes, the atmosphere has quit alot of pressure (.it could end up complicating your life quite a bit.

couldn't there be a "surface" in there somewhere, even if very fragile?

perhaps if there is no surface your ultimate doom would to be to sink all the way to the center then catch on fire due to its molten core of 7,000 °C

Answer 2

Brilliant answers - planets with NO surfaces? What are they, just big balls of dust? C'mon, they're huge, they mass quite a bit, somewhere under the atmosphere is a SURFACE, albeit it could be liquid or frozen, but it is certainly not just GASES down there, these are gas giant planets, but they're not entirely made of gases. You guys have quite the imagination.
But, if you WERE on the surface, the wind would tear you apart, it's a super-cyclonic wind force, if the temperature extremes didn't get you first. It will be a LONG time before humans ever develop a machine to penetrate deep enough to some sort of non-gaseous layer. So we may never know what is down there in our lifetime. Unless they develop space radar to "see" thru the gases in the atmospheres.

Answer 3

Or let's say you have some kind of space suit on. You would fall. And fall. And fall. Eventually the increasing pressure or extreme heat would overcome your suit and you would die. Quickly.

Note: even though the outer portions of the atmosphere are extremely cold, as others have said, the temperature and pressure build up as you fall in. There is no surface.

Edit: I should qualify that. There is probably a surface because there is a core, but that would be like the earth's core, not analogous to a surface like we think of it here on earth.

Answer 4

You would die very rapidly on a very blue from above planet. :D No oxygen, and if there were, it would be liquid. It's a gas giant, so your corpse would fall and fall until it reached a point of equilibrium, or its rocky core, depending on how dense it is. If equilibrium, it would probably crush you from pressure, if you weren't frozen rock solid by that point. If the rocky core, you'd probably shatter on impact.

Still, Neptune is a lovely shade of blue, isn't it?

Answer 5

You would say "Yay, I'm on Neptune!! Thank goodness this super spacesuit worked and I didn't die!!"
Then after a bit you'd say "I am so bored... I want to go home."

That's when you realise that you've locked the keys in the spaceship... Life's harsh.

Answer 6

Almost instantaneous death.
Sub- freezing temperatures, winds howling at over a thousand miles per hour, unbreathable atmosphere.

Not exactly a day at the beach.

Answer 7

you would instantly freeze to death and your lungs would explode

Answer 8

You'd die instantly.
