NGC 527, also occasionally referred to asPGC 5128 orPGC 5141, is alenticular galaxy located approximately 259 million light-years from theSolar System[4] in the constellationSculptor.[2] It was discovered on 1 September 1834 byastronomerJohn Herschel.[5]
Herschel discovered the object along withNGC 526.[6] The object was later catalogued byJohn Louis Emil Dreyer in the New General Catalogue, where the galaxy was described as "faint, small, a little extended, brighter middle, the following (eastern) of 2" with the other one being NGC 526.[5]
The galaxy has anapparent visual magnitude of 13.2 and can be classified as type SB0-a using theHubble Sequence.[2] The object's distance of roughly 260 million light-years from the Solar System can be estimated using itsredshift andHubble's law.[4]
NGC 527 has a much dimmer magnitude 14 companion galaxy (PGC 5142). Although this galaxy is not an NGC object, it is sometimes referred to as NGC 527B. The galaxy has an apparent size of 1.6' × 0.3' and a recessional velocity of approximately 5880 km/s.
