It may contain at least as many planets as well. Our solar system is about 27,000 light-years away from the galactic center. We are on the inner edge of one of the spirals. The Milky Way orbits at approximately 220 kilometers per second.

The Milky Way Galaxy is approximately 100,000 across light years in diameter, and on average, about 1,000 light years thick. Some scientists believe that the Milky Way can have a mass of 0.8–1.5×10^12 . The Milky Way has a relatively low surface brightness. The visible region of the Milky Way's Galactic plane occupies an area of the sky that includes 30 constellations. The center of the Milky Way lies in the direction of the constellation Sagittarius.
