Gravity holds the local group of galaxies together.
The Andromeda Galaxy is a member of the Local Group, which is a small cluster of galaxies that includes our Milky Way galaxy and a few dozen other smaller galaxies. The Local Group is part of the Virgo Supercluster, which is a larger structure of galaxies in the universe.
Our local group of galaxies is bound by gravity, although the large and small magellanic clouds nearby are moving fast enough they are probably just passing through. Our entire local group is also moving towards another big group of galaxies known as "the Great Attractor," which itself is bound by gravity. There are numerous clusters of galaxies bound by gravity throughout the hundred billion galaxies in our universe.
There are at least 27 known dwarf galaxies orbiting the Andromeda galaxy. These small galaxies are gravitationally bound to Andromeda and are much smaller in size and mass compared to the main galaxy.
Yes. The smallest galaxies may contain just a few million stars. Large galaxies like our own, the Milky Way, contain between 200 and 400 billion stars. The largest galaxies are Ellipticals, and may contain as many as 50 trillion stars.
Yes. Our local group of galaxies is made up of 3 larger galaxies (milky-way, Andromeda and M33) and several smaller or dwarf galaxies.
The local group of galaxies that include our Milky Way is called the "Local Group".The local group of galaxies that include our Milky Way is called the "Local Group".The local group of galaxies that include our Milky Way is called the "Local Group".The local group of galaxies that include our Milky Way is called the "Local Group".
A group of galaxies is called a galaxy cluster or galaxy group.
A group of galaxies is called a cluster.
We are part of the Local Group. The Local Group contains the Milky Way, two other major galaxies, and dozens of dwarf galaxies. The Local Groups is a group of galaxies which, as galaxies go, are close to us.
No. It has only 3 big spiral galaxies, but dozens of dwarf galaxies.
The Milky Way Galaxy is the second largest galaxy, after Andromeda, in the Local Group. The Triangulum Galaxy (a.k.a., the Star Wars galaxy) is the third largest. The Local Group contains about 30 galaxies, including dwarf galaxies.

The observable Universe has at least a hundred billion galaxies. The galaxies closest to us are part of the so-called "Local Group" (that is, the group that includes our galaxy); this Local Group includes our own galaxy (i.e., the Milky Way), the Andromeda Galaxy, the Triangulum Galaxy, and about 50 dwarf galaxies such as the Large Magellanic Cloud and the Small Magellanic Cloud. Then, of course, there are hundreds or thousands of galaxies "near-by" as distances between galaxies go, but outside of our Local Group.
