NGC 941 is an intermediate spiral galaxy in the constellation Cetus. It is an estimated 16.83 MPc (55 million light-years)[3] from the Milky Way and has a diameter of approximately 55,000 light years. The galaxies NGC 926, NGC 934, NGC 936, NGC 955 are located in the same sky area. NGC 941 was discovered by the astronomer William Herschel on 6 January 1785.[5][6]
One supernova has been observed in NGC 941: SN 2005ad (type II, mag. 17.4).[7][8]
