galantic center 

From Earth

Mass                                    - 800-1,500 M
Age                                      -  13.5 billion years old
Number of star's               - 400 billion star's

The milky way galaxy have been forming about 13.5 billion years ago and eating other small galaxies in it's way and the milky way has been for med in the denser area of the early universe.

The milky way is a small part of the local cluster of galaxy which is the part of the virgo super cluster.

The first of the star's that forms in the milky way galaxy is still on the globular cluster.

The milky way galaxies neighboring galaxy is Andromeda galaxy and the scientist predict that the milky way galaxy will collide to the Andromeda galaxy in 4 billion years also they says when it collide and makes a big elliptical galaxy.
