RA: 10h 08m 27.4s Dec: +12° 18′ 27″

Leo I is a dwarf spheroidal galaxy in Leo at 820,000 light-years. It is part of the Local Group of galaxies as satellite of our Milky Way (properly, Galaxy) . It was discovered in 1950 by Albert George Wilson on photographic plates of the Palomar Observatory Sky Survey (POSS). The proximity of Regulus (Alfa Leo) and the low brightness make it very difficult to observe it.
