Messier 110 (also known as M110 and NGC 205) is a dwarf spheroidal 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
Although Charles Messier never included the galaxy in his famous list, it was depicted by him, together with M32, on a drawing of the Andromeda galaxy; a label on the drawing indicates that Messier first observed NGC 205 on August 10, 1773.[5] The galaxy was independently discovered by Caroline Herschel on August 27, 1783; her brother William Herschel described her discovery in 1785.[5] The suggestion to assign the galaxy a Messier number was made by Kenneth Glyn Jones in 1967.[6]
In 1999, Johnson and Modjaz discovered a nova in M110.[7]
Unlike M32, NGC205 does not show evidence for a supermassive black hole at its center.[8]
