There is oxygen on other planets, but its either frozen due to low temperatures, or locked up in a solid molecular form (such as Iron oxide). Smaller planets cant hold it as an atmosphere, since it escapes the low gravity that they have.
There's not much oxygen on any planet except Earth. I mean "free" oxygen, not chemically combined with other elements. Obviously carbon dioxide contains oxygen combined with carbon, for example.
No, in recent history no human has set foot on any planet other than earth !
So far we have found no planet other than Earth that is suitable for human life.
All planets have gravity, not just Earth.
The Sun is many thousands of times closer to Earth than any other star.
Yes Mars has oxygen.
No, there is no oxygen on any other planet other than Earth because there is no planet life on the other planets.
Earth
Earth is the only planet known to have a significant amount of oxygen molecules in its atmosphere.
Yes. There is one planet with oxygen in its atmosphere: our home planet Earth.
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.
So far, we can only speak for our own planet, Earth; we're not aware of any other planet with either plant life or large quantities of free oxygen. On Earth, oxygen is produced by plants, which take in carbon dioxide and secrete oxygen, much as animals breathe in oxygen and breathe out carbon dioxide. We really are in symbiosis with our planet.

Earth's atmosphere contains a unique abundance of free oxygen, which is not found in significant quantities on any other planet in our solar system. This oxygen is produced mainly by photosynthesis from plants, making Earth's atmosphere distinct and supporting a wide variety of life forms.
1 . Earth is the only planet where life is known to exist..there is no other planet where life can exist !!2. Earth is the third planet which nearest to the sun and it has an atmosphere which consists of hydrogen ,oxygen and carbon dioxide which are required for the existence of human life whereas other planets do not have any such gases!!!
There isnt an exactly existance on any other planet than Earth
Earth is the only known planet with an oxygenated atmosphere.
