NGC 511, also occasionally referred to asPGC 5103 orUGC 936, is anelliptical galaxy in the constellationPisces.[2] It is located approximately 499 millionlight-years from theSolar System[4] and was discovered on 26 October 1876 byFrenchastronomerÉdouard Stephan.[5]
Stephan discovered the object with the 31" silver-glassreflecting telescope at theMarseille Observatory. He described his discovery as diffuse, with two faint stars on the west side. The description and position given in his notes matches UGC 936 and PGC 5103, thus the objects are widely recognized as the same.[6]John Louis Emil Dreyer, creator of theNew General Catalogue, described the galaxy as "extremely faint, very small, small (faint) star involved, small star attached", with the two stars being the objects to the west of NGC 511.[5]
The galaxy has an apparent size of 1.1 × 1.1 arcmins and arecessional velocity of approximately 10954 kilometers per second. It also contains multiple concentric rings. The distance of NGC 511 from the Solar System can be estimated usingHubble's law, which puts the object at nearly 500 million light-years from theSun.[5]
