DescriptionThe Little Bear winds around the north celestial pole like a smaller version of its great companion Ursa Major, though far fainter and less easily traced. In myth it is Arcas — the son of Zeus and the nymph Callisto — who was about to unknowingly kill his bear-mother when Zeus transformed him into a bear and placed them both among the stars. The tail of the Little Bear ends at Polaris — the North Star — the single most important navigational star in the northern hemisphere, lying within one degree of the celestial north pole. Polaris is itself a triple star system about 433 light-years away and a Cepheid variable; it will be closest to the true pole around the year 2100.
AsterismLittle Dipper: A smaller version of the Big Dipper; the end of the handle is Polaris.
