NGC 519, also occasionally referred to asPGC 5182, is anelliptical galaxy located approximately 242 million light-years from theSolar System[4] in the constellationCetus.[2] It was discovered by American astronomerLewis Swift on 20 November 1886.[6] It is a member of theAbell 194 galaxy cluster.[5]
Swift discovered the object along withNGC 530,538 and557 using a 16-inchrefractor telescope at the Warner Observatory.[7] It was later catalogued byJohn Louis Emil Dreyer in theNew General Catalogue, where the galaxy was described as "most extremely faint, very small, round, very difficult".[6]
The galaxy appears very dim in the sky as it only has anapparent visual magnitude of 14.4. It can be classified as type E using theHubble Sequence.[2] The object's distance of roughly 240 million light-years from the Solar System can be estimated using itsredshift andHubble's law.[4]
