NGC 5866B

NGC 5866B (also known as UGC 9769) is an intermediate spiral galaxy located about 52 million light-years away from Earth in the constellation of Draco.[1] The galaxy was discovered by Philip C. Keenan in March, 1935.[3] It is sometimes classified as a member of the NGC 5866 Group of galaxies [citation needed] and has a diameter of around 45.8 kly (14.05 kpc).[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 (LSB).[4][5]

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