**NGC 5866B** (also known as **[UGC](/source/Uppsala_General_Catalogue) 9769**) is an [intermediate spiral galaxy](/source/Intermediate_spiral_galaxy) located about 52 million light-years away from Earth in the constellation of [Draco](/source/Draco_(constellation)).[1] The galaxy was discovered by [Philip C. Keenan](/source/Philip_Childs_Keenan) in March, 1935.[3] It is sometimes classified as a member of the [NGC 5866 Group](/source/NGC_5866_Group) of galaxies [*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*] and has a diameter of around 45.8 [kly](/source/Light-year#Definitions) (14.05 [kpc](/source/Parsec#Parsecs_and_kiloparsecs)).[1] In visible light, the galaxy exhibits an overall bluish color and as it is relatively dim for a galaxy of its size, it is classified as a [low surface brightness galaxy](/source/Low_surface_brightness_galaxy) (LSB).[4][5]

NGC 5866B is located relatively close in the sky to the more well-known [NGC 5907](/source/NGC_5907) (Splinter Galaxy) and [NGC 5866](/source/NGC_5866) (Spindle Galaxy).[6]
