NGC 813 is a lenticular galaxy in the constellation Hydrus. It is estimated to be 390 million light-years from the Milky Way[3] and has a diameter of approximately 140,000 ly. NGC 813 was discovered on November 24, 1834 by the British astronomer John Herschel.[4][5]
One supernova, SN 2020abzv (type Ia, mag. 16.6), was discovered in NGC 813 on 9 December, 2020.[6]
