Triangulum II

(Tri II, Laevens 2)
(dwarf galaxy in the Local Group)

Triangulum II (Tri II or Laevens 2) is a dwarf galaxy of about 1000 stars, an ultra-faint dwarf galaxy (UFD) roughly 30 kpc from the center of the Milky Way, discovered in 2015 within the constellation, Triangulum. It was determined to have a very high mass considering its small star count, but a subsequent determination suggests its mass isn't so high.
