Is Andromeda a galaxy in the Milky Way?

Andromeda is the daughter of Cassiopeia and Cepheus. If you look up in the autumn night, you may find Andromeda. The Andromeda Nebula lies to the north of Quezon's sixteen stars. So Andromeda is a galaxy in the banking department? Next, come with me to the 88 constellations!

Andromeda is a galaxy in the banking system and belongs to the local galaxy group. It consists of the Milky Way and about 40 galaxies of different sizes, including Andromeda. Galaxy cluster is a huge celestial system composed of galaxies, gases and a large number of dark matter under the action of gravity. At present, tens of thousands of galaxy clusters have been discovered, which are as far away as 7 billion light years.

As we all know, there are Virgo Cluster, Late Constellation Cluster and Five Constellations Cluster. This ultra-local cluster includes the local cluster, the Virgo cluster, the Great Bear nebula and about 50 clusters.

The length and diameter are about 98 million to 245 million light years, which may be rotating and expanding. The cycle of the galaxy's rotation around the center of the cluster is 654.38+000 billion years. Of course, these are the views of some leading figures in international astronomy, so let's take him as the mainstream view. Because astronomy is so mysterious, disagreement is so common.
