Ursa Major (Great Bear (Dipper))

Month Best Visible

April

Hemisphere Visible

Northern


Except for Dubhe and Alkaid, the stars of the Big Dipper all have proper motions heading towards a common point in Sagittarius. A few other such stars have been identified, and together they are called the Ursa Major Moving Group. Mizar, a star in the Big Dipper, forms the famous optical double star with Alcor.

In Greek mythology, Zeus (the king of the gods) lusts after a young woman named Callisto, a nymph of Artemis. Hera, Zeus' jealous wife, transforms the beautiful Callisto into a bear. Callisto, while in bear form, later encounters her son Arcas. Arcas almost shoots the bear, but to avert the tragedy, Zeus hurls them both into the sky, forming Ursa Major.
