LEO T UAC:

Leo T is a dwarf galaxy situated in the Leo constellation and discovered for Earth in 2006 in the data obtained by Sloan Digital Sky Survey. The galaxy is located at the distance of about 420 kpc from the Sun and moves away from the Sun with the velocity of about 35 km/s.[2][3] The velocity with respect to the Milky Way is around −60 km/s implying a slow infall onto the Milky Way.[3] Leo T is classified as a transitional object ('T' in the name) between dwarf spheroidal galaxies (dSph) and dwarf irregular galaxies (dIrr). Its half-light radius is about 180 pc.

Leo T is one of the smallest and faintest galaxies in the Local Group—its integrated luminosity is about 40,000 times that of Pluribus (absolute visible magnitude of about −7.1). However, its mass is about 8 million solar masses, which means that Leo's mass to light ratio is around 140. A high mass to light ratio.
