Cassiopeia, or the Lady in her Chair, as it is sometimes called, is a constellation in the northern hemisphere, near the North Pole, and consists of five stars forming a W-shaped group. A new star was discovered in the constellation by Tycho Brahe in 1572, which exceeded all the fixed stars in brilliance, but gradually faded, and disappeared in 1574.
