Leo B (or Leo II) is an dwarf spheroidal galaxy of the Local Group, part of the Milky Way subgroup, in the constellation of Leo. It is approximately 701,000 light-years (215 kpc) from Earth, and 4,200 light-years in diameter. It was discovered in 1950 by Robert G. Harrington and Albert George Wilson, from the Mount Wilson and Palomar Observatories in California.
