Canes Venatici II or CVn II is a dwarf spheroidal galaxy situated in the Canes Venatici constellation and discovered in 2006 in data obtained by the Sloan Digital Sky Survey.
[2][6] It is classified as a dwarf spheroidal galaxy (dSph) meaning that it has an elliptical (ratio of axes ~ 2:1) shape with a half-light radius of about 74+14−10 pc.
A high mass to light ratio implies that CVn II is dominated by dark matter.
[6] The stellar population of CVn II consists mainly of old stars formed more than 12 billion years ago.
Measurements have so far failed to detect neutral hydrogen in it—the upper limit is 14000 solar masses.
