    Earth -- about 20% oxygen

    all other planets and moons -- oxygen about 0%

    It varies a lot. Why can't you google it?

    There is hardly any free oxygen anywhere but here.

    Oxygen is a very highly reactive gas. It can't stay in an atmosphere long unless something is constantly producing it, like life. So Earth is the only planet or moon or body with any oxygen.

    Near enough to zero, except on Earth.

    Other than earth, the planets that have oxygen (Mars, Venus) have it in the form of CO2 and/or water.  Not oxygen you could breathe.  The giant planets' atmospheres are more hydrogen, helium, and hydrocarbons.

    There are Various amounts on Various Planets

    Mercury has actually a very thin Atmosphere of Oxygen

    As has Jupiter's moon Europa

    Trace amounts elsewhere, even on Asteroids
