Detected in 1950 by Albert George Wilson on photographs with the 48-inch-Schmidt camera at Mount Palomar,Leo 1 was identified as beeing a Dwarf Galaxy,belonging to our Local Group of Galaxies.
It is very difficult to observe,because of the 1.st magnitude star alpha Leonis (Regulus) ,located only 12 arcminutes away.
Some 820.000 light-years away from us,this dSph-typed measures an apparent size of 9,8 × 7,4arcmin,shining with an visual brightness of 11.5mag.
