Constellation Cepheus looks like a house

• The constellation Cepheus represents a King. It is faint, but its distinctive shape makes it easy to locate if you look in the north on August evenings.
• Cepheus resembles the stick house we all drew as children - and that children today still draw - with a square for the base and a triangle for the roof. In the case of Cepheus, the tip of the roof (a star known as Gamma Cephei, or Errai) points generally northward.
• Star Errai: Future North Star
• In the sky, "northward" always means "toward the sky's north pole," or toward Polaris. Thus the roof of the house in Cepheus is pointing mostly

north, even though - in tonight's sky - that means it's pointing sideways and downward.
• In Greek mythology, Cepheus represents a King of Ethiopia. To find Cepheus, you might want to locate a more prominent constellation, Cassiopeia the Queen.
