NGC 519, also occasionally referred to as PGC 5182 is an elliptical galaxy located approximately 242 million light-years from the Solar System[4] in the constellation Cetus.[2] It was discovered on 20 November 1886 by astronomer Lewis Swift.[5]

Observation history[edit]

Swift discovered the object along with NGC 530, 538 and 557 using a 16-inch refractor telescope at the Warner Observatory.[6] It was later catalogued by John Louis Emil Dreyer in the New General Catalogue, where the galaxy was described as "most extremely faint, very small, round, very difficult".[5]

Description[edit]

The galaxy appears very dim in the sky as it only has an apparent visual magnitude of 14.4. It can be classified as type E using the Hubble Sequence.[2] The object's distance of roughly 240 million light-years from the Solar System can be estimated using its redshift and Hubble's law.[4]
