one that can float
no one lives on neptune and it would be impossible to. way too cold there
No, because it is very cold.
No, it is much too cold and has no solid surface.
An imaginary one.
An alien living on Neptune would need adaptations to withstand extreme cold temperatures, high atmospheric pressure, and toxic levels of methane and hydrogen. It would also need adaptations to survive in the absence of sunlight and the strong winds on the planet.
Because it's way too cold and people can barely live in Antarctica let alone Neptune, imagine 1,000 degrees below zero.
No. Even if you could overcome those problems, Neptune is a gas planet, so it does not have a surface.
No. Even if you had a space suit to provide air and protect you from the extreme cold, Neptune is a gas planet, meaning it has no surface to stand on.
If he was evolved for that gravity, pressure, temperature and atmospheric composition, he'd be asking how can an alien live on Earth? After all, from a Jovian standpoint, we are far too hot a planet, the gravity is too small to hold a properly thick atmosphere, and we have "poisonous" levels of Oxygen all over!
its nearly impossible to live on Neptune since it's a gas giant but if you could you would probably need to fly and withstand very cold weather plus breathe with no oxygen
No, Neptune is a gas giant composed primarily of hydrogen and helium with no solid surface. Its atmosphere is mainly hydrogen, helium, and methane, with no known vegetation able to survive in such extreme conditions.
No, no one can live on Neptune
