**NGC 5144** is an [unbarred spiral](/source/Unbarred_spiral_galaxy) [galaxy](/source/Galaxy) in the constellation of [Ursa Minor](/source/Ursa_Minor). It has a [velocity](/source/Velocity) of 3,202 ± 9 km/s corresponding to a [Hubble Distance](/source/Hubble's_law) of 47.2 ± 3.3 [megaparsecs](/source/Parsec) (154 million light-years).[2] It was discovered by [William Herschel](/source/William_Herschel) in May 1791.[3] It is a possible [field galaxy](/source/Field_galaxy) which does not belong to a group or cluster.[4]

NGC 5144 is also a [starburst galaxy](/source/Starburst_galaxy)[5] and classified as a [Markarian galaxy](/source/Markarian_galaxies) (designated as MRK 256), since its core emits large amounts of [ultraviolet light](/source/Ultraviolet).[6][7]
