Willman 1: Smallest Galaxy (aka; Dwarf Galaxy)
Willman 1 was first discovered in May 2003. It lies 120,000 light years away from our Milky Way Galaxy in the Ursa Major constellation and it is said to have a mass of only about 500,000 solar masses. It consists of old stars which are 10 billion years old and it is found in the constellation of Ursa Major. This extremely faint galaxy holds it name for being the third dimmest galaxy in the universe and therefore it is classified as an "ultra low-luminosity dwarf galaxy".
