Our Milky Way is 100,000 light years wide and at the center there is a black hole called Sagittarius A. Everything we can see with the bare eye is a

 small portion of the Milky Way Galaxy except for the Andromeda Galaxy. The reason is because the Andromeda Galaxy is 2.2x bigger than our

 Milky Way. The Milky Way is a galaxy which our Solar System is inside.

This Is The Milky Way from our eye. On its left you can see the Andromeda Galaxy but it looks like a big star.
