NGC 514 is a low-luminosity, [8] intermediate spiral galaxy in the equatorial constellation of Pisces, located at a distance of approximately 83 [3] million light-years from the Milky Way. It was discovered on 16 October 1784 by astronomer William Herschel. [9] The general form of the galaxy is specified by its morphological classification of SAB(rs)c, [5] which indicates it has a weak bar system at the core (SAB), an incomplete ring formation around the bar (rs), and somewhat loosely-wound spiral arms (c). This galaxy has an H II nucleus [10] with an extended region that displays weak emission lines in the optical range, but not in the near infrared. [5] The suspected supermassive black hole at the core has an estimated mass of 3.2×106  M☉ . [8]
