The Canes Venatici Dwarf (CVn dSph) is one of the most distant satellite galaxy of the Milky Way as of 2006 together with Leo I and Leo II.[2] It is a dwarf spheroidal galaxy in the Canes Venatici constellation, lying about 720,000 light-years away. The galaxy is approximately 6.5 kly (2 kpc)[2] across along its major axis and very faint. It is consists of a primarily old metal-poor stellar population.[2]
