Encyclopedic overview

NGC 3780 is a spiral galaxy in the constellation of Ursa Major. Its velocity with respect to the cosmic microwave background is 2,557±12 km/s, which corresponds to a Hubble distance of 123.0 ± 8.6 Mly (37.71 ± 2.65 Mpc). However, 10 non-redshift measurements give a closer mean distance of 109.65 ± 9.10 Mly (33.620 ± 2.789 Mpc). It was discovered by German-British astronomer William Herschel on 14 April 1789.

NGC 3780 is a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms. It also has an active galaxy nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.
