NGC 3370 is a spiral galaxy of Hubble type Sc in the constellation Leo on the ecliptic . It is about 53 million light years away from the Milky Way and about 45,000 light years in diameter .
The object was discovered on March 21, 1784 by the German-British astronomer Wilhelm Herschel .
On November 14, 1994, S. Van Dyk observed a supernova in this galaxy at the Leuschner Observatory Supernova Search , which was named SN 1994ae . This Type Ia supernova was one of the best-observed supernovae. The special thing about these type Ia supernovae is that they serve as so-called standard candles to determine the expansion of our universe .
