NGC 492, also occasionally referred to as PGC 4976 or GC 280, is a barred spiral galaxy in the constellation Pisces.

[1] It is located approximately 590 million light-years from Earth and was discovered on December 6, 1850 by Irish engineer Bindon Blood Stoney.

[2] Although John Dreyer, creator of the New General Catalogue, credits the discovery to astronomer William Parsons, 3rd Earl of Rosse, he notes that many of his claimed discoveries were made by one of his assistants.

[4] The object was initially described by Stoney as "extremely faint, small, round, 25" diameter, low surface brightness, no concentration".

The position noted was "on line with a mag 12 star 3.7' NW and a faint pair of mag 14-14.5 stars 2' NW".
