Messier 110 (also known as M110 and NGC 205) is a dwarf elliptical galaxy that is a satellite of the Andromeda Galaxy.[3] M110 contains some dust and hints of recent star formation, which is unusual for dwarf elliptical galaxies in general.[3]

[edit] History
M110 was serendipitously discovered on August 10, 1773 by Charles Messier, who was making observations of the Andromeda Galaxy at the time[4]. The galaxy was independently discovered by Caroline Herschel on August 27, 1783; her brother William Herschel described her discovery in 1785[4]. Although the galaxy was not originally included in Messier's first catalogue, it was later added in the twentieth century[4].
