Yes. Some giant elliptical galaxies contain tens of trillions of stars.
Nobody knows. We know there is lots like the Andromeda
There are no smaller galaxies in the Andromeda galaxy. In the Local group of galaxies to which Andromeda and the Milky Way are part of, there are around 30 smaller galaxies,
A galaxy cluster consists of several galaxy groups, each of which in turn contains several galaxies. So no; a galaxy cluster is MUCH bigger than any individual galaxy.
Milky way - "I bet i could take you on in a fight, Andromeda!" Andromeda - "Bring it on!" No galaxies do not think!
No.
Spiral galaxies
They are both spiral galaxies, except the Milky Way is a barred spiral and the Andromeda is a typical spiral galaxy. The Andromeda has at least twice as many stars as the Milky Way, and it has more mass. The galaxies are going to merge in 4 billion years, and now they are about 2 million light years apart.
andromeda(m31) Lmc Smc.
ALL of them, except the Milky Way and the Andromeda galaxies.
Three galaxies would be the Milky Way, Andromeda, and Comet Galaxy.
It is larger than the average galaxy, since the majority of galaxies are dwarf galaxies. However, there are still lots of galaxies that are larger than the Milky Way. For example, in our Local Group, the Andromeda Galaxy seems to be somewhat larger than our Milky Way.
