The stellar population of CVn II consists mainly of old stars formed more than 12 billion years ago. The metallicity of these old stars is also very low at
1380: 295:, which means that they contain 150 times less heavy elements than the Sun. The stars of CVn II were probably among the first stars to form in the 684:; Guhathakurta, P.; Frebel, A. (2008).
