The Ursa Minor Dwarf dwarf elliptical galaxy was discovered by A.G. Wilson of the Lowell Observatory in 1954. It is part of the Ursa Minor constellation, and a satellite galaxy to the Milky Way. The galaxy consists mainly of older stars and there appears to be little to no ongoing star formation in the Ursa Minor Dwarf galaxy.
[edit] Evolutionary history
In 1999, Mighell & Burke used the Hubble Space Telescope to confirm that the UMi system had a straight forward evolutionary history with a single ~2 billion years long burst of star formation around 11 billion years ago.[4]
