First of all, no human being has ever traveled to another planet, so that exact
question hasn't come up yet.
Twelve people have been to the moon, though. In order to breathe there, they did
exactly what they'd have to do on any planet away from the earth: They carried
tanks of oxygen, and whenever they went outside of their spacecraft, they wore
air-tight space suits with oxygen inside, a lot like Scuba divers.
Because they are just for aliens. Aliens don't have to breathe, but we do.
It would be difficult for humans to breathe on other planets as the atmospheres are very different from Earth's. For example, on Mars the atmosphere is mostly carbon dioxide with very little oxygen. Special equipment would be needed to survive on other planets.
As of now, the only planet known to have its own moon is Earth. Other planets in our solar system have moons but no planets of their own. In our solar system, moons primarily orbit around planets rather than planets orbiting around other planets.
Jovian planets
Earth is the only planet we know of that has life because on other planets the atmosphere won't let us breathe in it and they are either too cold or too hot. ~Dan
no
Of course they can - as long as they are in their spacesuits or habitats. Out in the open? No.

it would not be helpful because there is no air so you cant breathe
No one knows at the moment why Jupiter is a big planet, other than the theory ogf how other planets where dust came together to form the planets, and it could just be it took more of it to form. What we do know is that you can not breathe in Jupiter in the same way you can not breathe on the Moon, whihc is no development of an atmosphere.
There isn't any oxygen, or plants to create it..Because other planets do not have the righ gases. Earth has enough O2 to breath.
That all of them scientists have found do not have the air we breathe
when you breathe out, plants breathe in.
Yes. Earth & Qo'nos are Class M planets.
Yes.
Of the planets of our solar system, only Earth itself is easy to live on. None of the other planets are habitable without a protective sealed habitat. Of the other planets, Mars may be easiest; we'll need to build the sealed habitat, and convert some of the iron oxide in the soil to oxygen that we can breathe, but it won't be INCREDIBLY cold, or have poisonous atmosphere, or crushing pressure. And after we've figured out how to live on the Moon, Mars will be fairly straightforward.
