The Milky Way galaxy is the largest and most famous of all galaxies, but it's not alone. There are over 100 billion stars in our galaxy, which makes up about 4% of the total number of stars in the observable universe. However, there are many more galaxies out there, each with its own unique set of stars and planets.

One of the most well-known groups of galaxies is the Local Group, which includes our own Milky Way galaxy along with several other nearby galaxies such as Andromeda, M31, and M33. The Local Group is estimated to contain around 250 billion stars, making it the third-largest galaxy cluster in the universe.

Another important group of galaxies is the Virgo cluster, which contains around 100 billion stars and is located about 6 million light-years away from us. The Virgo cluster is also one of the oldest and most massive clusters of galaxies in the universe, dating back to the early days of the universe itself.

There are also many smaller groups of galaxies, including the Ursa Major cluster, which contains around 100 billion stars and is located about 100,000 light-years away from us. The Ursa Major cluster is known for its brightest star, Proxima Centauri, which is only about 4.2 light-years away from us.

In addition to these larger clusters, there are also many smaller groups of galaxies that are scattered throughout the universe. These include the Fornax cluster, which contains around 100 billion stars and is located about 100,000 light-years away from us; the Coma cluster, which contains around 100 billion stars and is located about 100,000 light-years away from us; and the Sculptor cluster, which contains around 100 billion stars and is located about 100,000 light-years away from us.

Overall, there are countless galaxies out there in the universe, each with its own unique set of stars and planets. From the largest and most famous galaxies like the Milky Way to the smaller groups of galaxies scattered throughout the cosmos, there is no shortage of wonder and awe when it comes to exploring the vast expanse of space that surrounds us.
