NGC 3310, also known as the Bow and Arrow Galaxy, is a grand design spiral galaxy in the constellation Ursa Major. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . However, eight non-redshift measurements give a closer mean distance of . It was discovered by German-British astronomer William Herschel on 12 April 1789.
NGC 3310 is a starburst galaxy and it is likely that it collided with one of its satellite galaxies about 100 million years ago, triggering widespread star formation. The ring clusters of NGC 3310 have been undergoing starburst activity for at least the last 40 million years.
Supernovae
Four 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. SN 1991N (Type Ib/c, mag. 15) was discovered by the Berkeley Automated Supernova Search on 29 March 1991 at an offset of east and south of the galactic nucleus. SN 2021gmj (TypeII-P, mag. 15.1) was discovered by the Distance Less Than 40 Mpc Survey (DLT40) on 20 March 2021. SN 2026sqf (TypeIa-CSM, mag. 12.9) was discovered by American amateur astronomer Patrick Wiggins on 8 July 2026. It had originally been classified as TypeII, but later analysis concluded it to be type Type Ia-CSM, the closest yet known of this kind. SN 2026sqf is part of the Unistellar "cosmic cataclysms" smart telescope tracking project.
