What would happen to a human on Neptune?

Answer 1

If you went to Neptune, you would be squished flat dead.

Answer 2

They could only be in Neptune's atmosphere. Neptune is gas down as far as the core and so there is technically no surface. Therefore, a human could never be 'on' Neptune, on 'in' its atmosphere, and a human on Neptune would be a bit heavier, but not to much. There isn't anything to eat. It would be colder than most could imagine. Cold enough that nitrogen, which is an atmospheric gas here on earth, would be a liquid on Neptune. A person couldn't wear enough clothing to be protected outside on the surface. Any building there would have to be insulated in a way no building contractors here on earth have ever done. You'd need some serious heat in that building. Very serious heat. Oh, and with wind on Neptune ripping at something like 2100 kilometers per hour, it would be really tough to keep a structure in one place.

Answer 3

Probably not. A human on Neptune would be a bit heavier, but not to much. There isn't anything to eat. It would be colder than most could imagine. Cold enough that nitrogen, which is an atmospheric gas here on earth, would be a liquid on Neptune. A person couldn't wear enough clothing to be protected outside on the surface. Any building there would have to be insulated in a way no building contractors here on earth have ever done. You'd need some serious heat in that building. Very serious heat. Oh, and with wind on Neptune ripping at something like 2100 kilometers per hour, it would be really tough to keep a structure in one place. Neptune's winds have been clocked at over 1300 miles per hour. That's faster than the speed of sound in air on earth. Just as a closer, you'd have to take your own air and reprocess it. Neptune's atmosphere is almost all hydrogen and helium. Don't expect the real estate market on Neptune to be booming any time soon. It's an extraordinarily hostile place.

AnswerThere is nothing to survive on. Neptune is a gas giant, with a small inner core of molten rock, and a mantle of ice, which is more like a super-dense fluid. See link.

Answer 4

A human on Neptune would not survive due to its extremely cold temperatures, high levels of atmospheric pressure, and lack of oxygen. The planet's atmosphere is mostly made up of hydrogen and helium, with trace amounts of methane that would be toxic to humans.

Answer 5

they would freeze to death and suficate because no air to breathe

Answer 6

If you went to Neptune, you would be squished flat dead.

Answer 7

They would freeze to death.

Answer 8

the "temperature"

Answer 9

i don't have any idea
