Cassiopeia

Cassiopeia, the Lady in her Chair, a constellation in the northern hemisphere, near Cepheus, and not far from the north pole, named after the mother of Andromeda. It is marked by five stars of the third magnitude, forming a figure like a W. In the year 1572 there all at once appeared in Cassiopeia a new star, which when first noticed by Tycho Brahé exceeded in brightness all the fixed stars, and nearly equalled Venus. The star gradually diminished in lustre, and disappeared in March 1574.
