Neptune is a gas giant, so it is uninhabitable to humans.
Since the planet Neptune is a gas giant, it is not a hospitable place for growing food, and I greatly doubt that anyone will ever live there or grow food there, however, the moons of Neptune, which are still not easy places to live, are nonetheless much easier places to live than Neptune, and perhaps people will some day live there and grow food there. Although even that is unlikely.
the only way for aliens to live on Neptune is they have to be able to survive on a planet like neptune. it wouldn't be a very good choice unless the could live on a freezing and mostly gas planet.
no because planet neptune does not have enough atmosphere for human to breath in
No. The planet has no oxygen.
No. Earth is the only planet in this solar system that has life.
If you mean the planet Neptune, there are no people there, as the only place off Earth we have been is the Moon. If and when people do get there, they will have to live in sealed environments, probably in orbit. There is no oxygen nor hard surface on Neptune and it's extremely cold. If you mean Neptune City, New Jersey, there are plenty of good places to eat:https://www.tripadvisor.co.uk/Restaurants-g46660-Neptune_City_New_Jersey.html
you wouldhave to live in a cool house
It doesn't say in the movie, but someone suggested Uranus or Neptune.
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.
No, because Neptune is a gas planet and if you were to walk on it, you would actually sink into it. Furthermore Neptune is -218 degrees Celsius so you wud like freeze to death. there food nor any means of growing food and it would be hard to reproduce on a gas planet.
Earth is the only planet that has suitable conditions for things to live on hope that helped
