Canes Venatici (abbr. CVn, gen. Canum Venaticorum)
The Hunting Dogs; a small, faint northern constellation, surrounded by Ursa Major to the north, Boötes to the east, and Coma Berenices to the south. Its only star brighter than magnitude 4.0 is Alpha2 CVn, or Cor Caroli (visual magnitude 2.89; absolute magnitude 0.89; spectral type A0Vp; distance 82 light-years; R.A. 12h 56m 2s, Dec. +38° 19' 03"). Its second brightest star, Chara, however, is of great interest because it has been ranked as the nearest Sunlike star most likely support life. Canes Venatici is particularly well-endowed with galaxies. See below for details of the constellation's interesting deep sky objects.
