Corvus (constellation)
Corvus (Latin - the crow, or raven) 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, and also counts among the 88 modern constellations.
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 Terra.
