Corvus is a small constellation in the Southern Celestial Hemisphere.
Its name means "raven" in Latin. In the Babylonian star catalogues
dating from at least 1100 BCE, it was called the Babylonian Raven. One
of the 48 constellations listed by the 2nd-century astronomer Ptolemy,
it depicts a raven, a bird associated with stories about the god Apollo,
perched on the back of Hydra the water snake. It is also bordered by the
constellations Virgo and Crater. Its four brightest stars, Gamma, Delta,
Epsilon, and Beta Corvi, form a distinctive quadrilateral in the night
sky. With an apparent magnitude of 2.59, Gamma Corvi—also known as
Gienah—is the brightest star in the constellation. It is an aging blue
giant around four times as massive as the Sun. The young star Eta Corvi
has been found to have two debris disks. Three star systems have
exoplanets, and a fourth planetary system is unconfirmed. TV Corvi is a
dwarf nova—a white dwarf and brown dwarf in very close orbit.
