The Milky Way Galaxy……our home galaxy!!!!

21 Jul

The Milky Way Galaxy is a spiral galaxy. This type of galaxy has a center with arms of clustered stars spiraling out. The Milky Way Galaxy is estimated to have anywhere from 200 billion to 400 billion stars. If that does not give you an idea of how big it is, the Milky Way is roughly 100,000 light years in diameter. The Sun is far from the center of the Galaxy, halfway to the edge of the Galaxy along the Orion spiral arm. The Sun is revolving around the center of the Galaxy at a speed of half a million miles per hour, yet it will still take 200 million years for it to go around once.
