The story of the word

Zeus seduced her, a goddess turned her into a bear, and her own son nearly speared her before both were fixed in the sky as the Great and Little Bear. Simon Marius drew his four moon names from Jupiter's love affairs, publishing them in 1614. The moon is the most heavily cratered object yet surveyed, its surface so old it has recorded almost everything that ever hit it.
