Our galaxy is considered to be a typical spiral galaxy about 75,000 light years in diameter. It is a member of the so-called ‘Local Group’ of about 20 galaxies, which is about 6 million light years in extent and which is dominated at one end by our own galaxy and at the other by the much larger Andromeda galaxy.
