Description

Donatiello I is named after its discoverer, Italian amateur astrophotographer Giuseppe Donatiello, and is abbreviated to "Do I". The galaxy's nickname, "Mirach's Goblin", is a reference to the nearby dwarf lenticular galaxy NGC 404, with which it may be physically associated. NGC 404 is nicknamed "Mirach's Ghost" due to its proximity to the second magnitude star Mirach.
