Messier 110 - Dwarf Elliptical Galaxy

Messier 110 - Dwarf Elliptical Galaxy

Messier 110, also known as NGC 205, is a dwarf elliptical galaxy that is a satellite of the Andromeda Galaxy in the Local Group.

Charles Messier never included the galaxy in his list, but it was depicted by him, together with Messier 32, on his drawing of "Nébuleuse D'Andromède", later known as the Andromeda Galaxy. A label of the drawing indicates that Messier first saw the object in 1773. Messier 110 was independently discovered by Caroline Herschel on August 27, 1783; her brother William Herschel described her discovery in 1785. The suggestion to assign the galaxy a Messier number was made by Kenneth Glyn Jones in 1967, making it the last member of the Messier List.

This galaxy has a classification as a dwarf elliptical galaxy with a flattening of 50%. It is designated peculiar (pec) due to patches of dust and young blue stars near its center. This is unusual for dwarf elliptical galaxies in general, and the reason is unclear. Unlike Messier 32, Messier 110 lacks evidence for a supermassive black hole at its center.
