The Milky Way is about 100,000 light years across. 100,000 light years= 9,460,000,000,000 km. The sun is about midway. The Milky Way is visible from Earth as a band of light in the night sky, but the low brightness makes it difficult to see through the pollution. Our planet is home to 8 planets(formely 9) and a fair few dwarf planets.

Andromeda is the nearest spiral galaxy and is about twice as big as the Milky Way.
