NGC 3310
Galaxy in the constellation Ursa Major
From Wikipedia, the free encyclopedia
NGC 3310 is a grand design spiral galaxy in the constellation Ursa Major. It is a starburst galaxy and it is likely that NGC 3310 collided with one of its satellite galaxies about 100 million years ago, triggering widespread star formation. It is thought to be located approximately 46 million light-years away from the Earth, and is thought to be about 22,000 light-years wide.

The ring clusters of NGC 3310 have been undergoing starburst activity for at least the last 40 million years.[4]
Supernovae
Three supernovae have been discovered in NGC 3310:
- SN 1974C (type unknown, mag. 16.5) was discovered by Pieter van der Kruit and Halton Arp on 25 February 1974.[5][6] [Note: some sources incorrectly list the discovery date as 26 February.]
- SN 1991N (Type Ib/c, mag. 15) was discovered by the Berkeley Automated Supernova Search on 29 March 1991 at an offset of 5″ east and 7″ south of the galactic nucleus.[7][8]
- SN 2021gmj (Type IIP, mag.15.1) was discovered by the Distance Less Than 40 Mpc Survey (DLT40) on 20 March 2021.[9]
