Messier 74 (also known as NGC 628 called) is a spiral galaxy of Hubble type SA (s) c? in the constellation Pisces on the ecliptic . It has an apparent size of 10.5 '× 9.5' and an apparent magnitude of +9.1 mag. The distance from M 74 is not exactly known, values around 30 million light years are given.
Three supernovae were observed in M74 in the 21st century ( SN 2002ap , SN 2003gd and SN 2013ej ).
The galaxy was discovered by Pierre Méchain in September 1780 and reported to Charles Messier for cataloging.
