Circumpolar (northern)

A huge and dim constellation located between Perseus and Ursa Major.

Trace an imaginary line from the Big Bear’s pointers on past Polaris. At an equal distance on the opposite side from the Big Dipper is Cassiopeia (KASS-ee-oh-PAY-uh), an ancient Queen of Ethiopia.

As she sits on her W-shaped throne she circles round and round the pole. Like the Big Dipper, Cassiopeia is circumpolar and therefore visible no matter what the season or time of night. In the fall Cassiopeia is in the shape of a W and in the Spring she is in the shape of a M.

The Ethiopian king, Cepheus (SEE-fee-us), is a circumpolar constellation that sits atop the Milky Way on a throne near his queen Cassiopeia. The legs and seat of his throne make a rough square on the Ursa Major side of Cassiopeia. Cepheus looks like a house (or throne) sitting on the Milky Way. The back of the seat comes to a point at the top above his head.

Draco occupies over 1,000 square degrees in the sky as it winds from the Pointers of Ursa Minor nearly to Vega in Lyra. Yet it has no bright stars.

Use the pointer stars of the Big Dipper to find Polaris, the tip of Ursa Minor’s tail. The whole sky seems to rotate around Polaris once a day, since it is located near the north celestial pole. The two other bright stars of Ursa Minor represent the far edge of its dipper, and lie nearer to the Big Dipper.
