If you want to picture exactly how large our very own Milky Way is, imagine the Solar System were the size of a quarter. The Sun would be a microscopic piece of dust and the Milky Way would be the size of the United States. The Milky Way rotates at about 170 miles per second so the location you were an hour ago is about 600,000 miles away the universe is a true beaut
