NGC 3370 (also known as UGC 5887 or Silverado Galaxy^[2]) is a spiral galaxy about 98 million light-years away in the constellation Leo. It is comparable to our own Milky Way both in diameter (100,000 light years) and mass (10¹¹ solar masses). NGC 3370 exhibits an intricate spiral arm structure surrounding a poorly defined nucleus.

History

NGC 3370 was likely discovered by William Herschel, who provided it with the designation II 81.^{[citation needed]} His son John later designated it 750. William Herschel cataloged II 80 to NGC 3348 before and II 82 to NGC 3455 after NGC 3370.^{[citation needed]}

The object has a surface brightness of 13 and a position angle (PA) of 140°.

On November 14, 1994, S. Van Dyk and the Leuschner Observatory Supernova Search discovered a supernova in NGC 3370 at 10^h 44^m 21.52^s +17° 32′ 20.7′′, designated SN 1994ae.^[3] SN 1994ae was a type Ia supernova, and one of the nearest and best observed since the advent of modern digital detectors.^{[citation needed]} The maximal light of the supernova was estimated to have occurred between November 30 and December 1^{[citation needed]}, peaking at visual magnitude 13.^[3]
