Messier 110 (also known as M110 and NGC 205) is a dwarf elliptical galaxy that is a satellite of the Andromeda Galaxy.[4] M110 contains some dust and hints of recent star formation, which is unusual for dwarf elliptical galaxies in general.[4]

[edit] History
M110 was serendipitously discovered on August 10, 1773 by Charles Messier, who was making observations of the Andromeda Galaxy at the time.[5] The galaxy was independently discovered by Caroline Herschel on August 27, 1783; her brother William Herschel described her discovery in 1785.[5] Although the galaxy was not originally included in Messier's first catalogue, it was later added by Kenneth Glyn Jones in 1966.[5][6] M110 remains the last object added to the Messier catalog.
In 1999, Johnson and Modjaz discovered a supernova in M110.[7]
