King Cepheus

Cepheus was a king in Greek mythology. His wife was Cassiopeia and his daughter was Andromeda. Cassiopeia once said some things to make the sea god angry. A monster was sent up to eat Andromeda, but Perseus saved her. Today, all five objects are constellations.

Cepheus looks like a house. The roof's tip is a special star called a cepheid. It is used by scientists to measure long distances. Another cepheid is just below the constellation. This red star would be the North Star if we lived on Mars!

Cepheus is full of neat things like nebulae, clusters and galaxies. You will need a telescope to see them!
