Galaxies - NASA Science
Galaxies consist of stars, planets, and vast clouds of gas and dust, all bound together by gravity. The largest contain trillions of stars and can be more than a million light-years across. The smallest can contain a few thousand stars and span just a few hundred light-years.
Galaxy - Wikipedia
Galaxies, averaging an estimated 100 million stars, [3] range in size from dwarfs with less than a thousand stars [4] to the largest galaxies known — supergiants with one hundred trillion stars, each orbiting its galaxy's center of mass.
