Andromeda is a constellation in the northern sky. It is named after the princess Andromeda in Greek mythology. It is sometimes called "the Chained Lady" or "the Chained Woman" in English.[1] It has also been called Persea ("Perseus's wife")[1] or Cepheis ("Cepheus's daughter").[1] The astronomer named Ptolemy listed Andromeda when he made a list of 48 constellations. It is also one of the 88 constellations made by the International Astronomical Union.[2]
The Andromeda Galaxy is inside Andromeda, so it has the same name. It is the closest spiral galaxy to Earth.[3] The brightest star in Andromeda is called Alpha Andromedae, which is a binary star.[4]
