The Milky Way Galaxy, The Galaxy that we call home. Once thought to be what encompassed the entire Universe, is now known as one of many like it. The Milky Way Galaxy is in fact one of about 100 Billion Galaxies! So much for The Milky Way being The Universe. Some of these other galaxies include, The Andromeda Galaxy, Sombrero Galaxy, Baby Boom Galaxy, Star Fish Galaxy & Virgo Stellar Stream. The Milky Way Galaxy has over 250 Billion plus or minus 150 Billion Stars in it's perimeters. It's radius is 52,850 Light years and The distance of The Sun to it's, likely Black Hole, Center is 26.4 plus minus 1.0 kly. And it takes about 240 Mega Light Years for The Sun to revolve around the center of The Milky Way Galaxy. Yes, even The Sun revolves around something.
The Name Milky Way, comes from the way we see the galaxy from Earth. Since we are inside of the actual galaxy, our view of its shape is quite obscured. Though we know now that The Milky Way Galaxy is a barred spiral galaxy, which means it is a spiral galaxy except that in the center is a bar shape of light. In Latin it is translated to via lactea and in Greek it is galaxias kyklos which translates from Greek to Milky Circle.
