NGC 527, also occasionally referred to as PGC 5128 or PGC 5141, is a lenticular galaxy located approximately 259 million light-years from the Solar System [4] in the constellation Sculptor. [2] It was discovered on 1 September 1834 by astronomer John Herschel. [5]
Observation history
Herschel discovered the object along with NGC 526. [6] The object was later catalogued by John 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]
Description
The galaxy has an apparent visual magnitude of 13.2 and can be classified as type SB0-a using the Hubble Sequence. [2] The object's distance of roughly 260 million light-years from the Solar System can be estimated using its redshift and Hubble's law. [4]
Companion galaxy PGC 5142
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.
