It's rare when star patterns on our sky's dome have anything to do with real associations of stars in space, but the 3 stars near tonight's moon - known as the Crown of the Scorpion - are thought to be loosely bound by gravity. All 3 are located at approximately the same distance, about 500 light-years away. They're members of the Scorpius-Centaurus group, which was first recognized by astronomers in the early part of the 20th century.
