Donatiello I, also known as Mirach's Goblin, is a dwarf spheroidal galaxy located in the constellation Andromeda, at between 8.1 and 11.4 million light-years from Earth. It is a possible satellite galaxy of the dwarf lenticular galaxy NGC 404, "Mirach's Ghost", which is located 60 arcminutes away.
It is otherwise one of the most isolated dwarf spheroidal galaxies known, being physically located around 211,000 light-years away from NGC 404.
The galaxy is named after its discoverer, amateur astrophotographer Giuseppe Donatiello, who sighted the galaxy in a 2016 review of his archival long exposures from 2010 and 2013. Follow-up observations with the Roque de los Muchachos Observatory led to a scientific paper on its discovery being published in December 2018. (Wikipedia)
