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.

[5] 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] The galaxy appears very dim in the sky as it only has an apparent visual magnitude of 14.4.

[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.
