DescriptionThe Southern Crown is one of the smallest but oldest constellations, known to the ancient Greeks as a wreath or crown lying at the feet of the Archer (Sagittarius). Some myths associate it with the crown Sagittarius wears, others with a laurel wreath. It sits in an exceptionally rich region of the Milky Way near the galactic center. The constellation contains the Corona Australis Molecular Cloud — one of the nearest and most active star-forming regions to our Solar System at about 430 light-years away. Despite its small size it has been recognized since antiquity and is one of Ptolemy's original 48 constellations.
