Leo II

Leo II (or Leo B) is a dwarf spheroidal galaxy about 690,000 light-years away, one of the known satellite galaxies of the Milky Way. It is thought to have a core radius of 178 ± 13 pc and a tidal radius of 632 ± 32 pc.

Leo II consists largely of metal-poor older stars, a sign that it has survived the galactic cannibalism under which massive galaxies (e.g., the Milky Way) consume smaller galaxies to attain their extensive size. [[category:Dwarf spheroidal galaxies]
