NGC 550 is a spiral galaxy in the constellation Cetus. It is estimated to be about 300 million light-years from the Milky Way[3] and has a diameter of approximately 110,000 light years. The German-British astronomer William Herschel discovered it on 8 October 1785.[4][5][6]
One supernova has been observed in NGC 550: SN 1961Q (type unknown, mag. 17.2) was discovered by Milton Humason on 30 November 1961.[7][8]
