NGC 105 is a spiral galaxy estimated to be about 240 million light-years away in the constellation of Pisces. It was discovered by Édouard Stephan in 1884 and its apparent magnitude is 14.1.[4]
Two supernovae have been observed in NGC 105: SN 1997cw (type Ia, mag. 16.5),[5] and SN 2007A (type Ia, mag. 16).[6]
