Planets orbit stars, stars orbit a galaxy. Planets are not "on" anything. A lot of stars out there have planets - we are just finding out how many now that we have better techniques to find them. So probably all galaxies have at least some stars with planets.
The closest galaxy that has planets is the Andromeda galaxy. It is the nearest galactic neighbor to the earth. The Milky Way has other planets too.
The Whirlpool Galaxy, also known as M51, is a spiral galaxy about 23 million light-years away. While it is known to have many stars, it is difficult to confirm the presence of planets within other galaxies due to the large distances involved. So, as of now, there is no confirmed information on planets in the Whirlpool Galaxy.
Probably, but impossible to tell as we are only just seeing planets within our own galaxy.
That would be a galaxy. Our solar system is part of the Milky Way galaxy, which contains billions of stars, planets, and other celestial objects.
our solar system belongs to the milky way Galaxy
The planets are part of the galaxy.
It is possible that every galaxy has some planets. We just are starting to detect some planets in other galaxies.
The planets we know of, some 300 now, are all in the Milky Way galaxy.
Planets are not necessarily in a galaxy but chances are very slim that in a galaxy that is not just newly forming there would not be any exoplanets.
We expect the Andromeda galaxy to be just like our own Milky Way galaxy. We can see stars (suns) in the Andromeda Galaxy and just as stars have planets orbiting them in our galaxy, we believe that there must be planets also orbiting stars in the Andromeda galaxy.
The Andromeda galaxy is a separate galaxy from our Milky Way and has its own set of planets. However, due to the vast distance between our galaxies, we are currently unable to observe individual planets in the Andromeda galaxy.
No. I don't believe any planets have been detected outside of our Galaxy. Within our Galaxy, planets are detected by inference not visual techniques. See link for lists of known extrasolar planets
There are billions of planets and moons in the Star Wars galaxy.
The galaxy is not a planet. The galaxy is MADE of millions and millions of stars and planets.
It is extremely likely, but we cannot yet find planets from that far away. All the planets we have found to date are in our own galaxy. The Andromeda galaxy is 2.5 million light years away whereas our galaxy is about 100,000 light years across.

There are no known planets in any galaxy other than our own. While it is doubtless that other galaxies, including the cigar galaxy, contain planets they are much too far away fur us to detect them.
