My galaxy, the Milky Way (which is also your galaxy; I am sure that the person asking this question is not a visitor from another galaxy) has not been examined in enough detail to say even how many planets it contains, much less how many moons orbit those planets. But given that our own solar system has numerous moons, and there are billions of other stars in the galaxy which probably also have planets and moons, at a wild guess I could estimate possibly a hundred billion moons.
there are 139 moons altogether.
There are billions of planets and moons in the Star Wars galaxy.
It has 12 moons.
an infinite number
It is not known. The Andromeda Galaxy contains about a trillion stars, many of which certainly have planets, though we don't know how many. Many of the planets likely have moons. All told, there are likely several hundred billion to several trillion moons in the Andromeda Galaxy.
Based on this riddle, Saturn has 18 moons.
In our Solar System, 173 moons around planets are recognized, as well as over 200 moons around minor planets.
Very probable this number is not known.
The Andromeda galaxy, also known as M31, has at least 27 known dwarf galaxies orbiting around it, which can be considered its "moons".
No, the Andromeda Galaxy does not have any moons. Moons typically orbit around planets, not around galaxies. The Andromeda Galaxy is a spiral galaxy similar to our Milky Way and contains billions of stars but no moons.
There are about 100 billion stars in the Milky Way Galaxy. We only know of moons in the solar system - 169 of them.
All of the ones we know about and have named are in our Galaxy.
