The Milky Way Galaxy

The Milky Way Galaxy is so large that since the creation of our solar system approximately 4.6 billion years ago., it has only circled or orbited the center of the Milky Way about twenty times.  Our Solar system (the sun  and its nine planets) moves in an orbit around the center of the milky way at about 140 ,miles per second, which means it takes the Sun about 230 million years to complete one orbit.
As seen from earth, the Milky Way looks like a giant frisbee that bulges in the center as it spins in space.  Out solar system is in the lower part of a trailing arm of the Milky Way Galaxy, A spiral Galaxy with a span of about 100,000 light years of nearly 600,000 trillion miles.
As least 100-200 billion stars lie within the Milk Way which only a medium sized galaxy among trillions of other galaxies.
The starts at the center of the galaxy are very crowded together, and if the Earth were in this region we would see millions of very bright stars, (many larger that our sun) and it would never be dark.
