M3 is one of the brightest globular clusters in the sky. It contains around 300,000 stars and spans almost 200 light years. From its distance of 34,000 light years, it is still barely visible to the naked eye from very dark locations. Nearly 150 of these clusters orbit the Milky Way Galaxy, but only a handful are as brilliant as M3 when viewed from the earth.
