Hi Logan,
Other galaxies, like ours, contain billions of stars. Many of these are similar to the Sun. We don't know yet if they have planets around them, but we have started discovering that many stars in our galaxy have planets, so that is probably true in other galaxies as well.
cheers,
Terry

How big are the planets that orbit these stars? And how small is the smallest galaxy?
