About Psi UMa

Description

Psi Ursae Majoris is an orange giant of spectral type K1III at magnitude 3.01 in Ursa Major. It has a surface temperature of about 4,600 K and a warm orange hue. It lies in the body of the Great Bear, south of the more prominent Big Dipper asterism.

Observing Tips

Psi UMa is located in the hindquarter of the Great Bear, south of the Dipper's bowl stars. It is visible year-round from mid-northern latitudes as part of the circumpolar constellation Ursa Major. Its orange color is apparent in binoculars. Best placed in the evening sky from February through July.

History

Psi Ursae Majoris has no traditional proper name. It lies in the body of the Bear, part of the extended figure that is much larger than the familiar Big Dipper asterism. Ursa Major is one of the oldest recognized constellations, known to cultures around the world under various guises — a bear, a plough, a wagon, or a ladle.

Fun Facts

Many people are surprised to learn that Ursa Major extends far beyond the Big Dipper — the Dipper forms only the Bear's back and tail, while many additional stars outline its head, legs, and feet. Psi UMa is one of these 'body' stars that most casual observers never notice.
