Corvus (pronounced /ˈkɔrvəs/, Latin: raven or crow) is a small southern constellation with only 11 stars visible to the naked eye (brighter than magnitude 5.5). It was one of the 48 constellations listed by Ptolemy, who only counted 7 stars.[1] It is among the 88 modern constellations.

[edit] Notable stars
δ, γ, ε, and β form the 'sail' asterism; and γ and δ serve as pointers toward Spica.
[edit] Notable deep sky objects
Corvus contains no Messier objects.
The Ringtail peculiar galaxy consists of the possibly colliding NGC 4038 and NGC 4039, and appears to have a heart shape as seen from Earth.
The center of Corvus is home to a Planetary nebula NGC 4361. The nebula itself resembles a small elliptical galaxy, but the magnitude 13 center star gives away its true nature.
