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 1,169±13 km/s, which corresponds to a Hubble distance of 56.3 ± 4.0 Mly (17.25 ± 1.22 Mpc). However, eight non-redshift measurements give a closer mean distance of 42.73 ± 3.72 Mly (13.100 ± 1.142 Mpc). 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.

Four supernovae have been discovered in NGC 3310:
