NGC 3610 is an elliptical galaxy in the constellation Ursa Major.[6] It was discovered on 8 April 1793 by German-British astronomer William Herschel.[7] This galaxy is located at a distance of 106 million light-years (32.5 Mpc) from the Milky Way,[4] and is receding with a galacto-centric radial velocity of 1,819 km/s.[3]

NGC 3610 is a relatively young elliptical galaxy which has not yet lost its disk.[6] It has a morphological classification of E5,[8] indicating a 2:1 ratio between the major and minor axes of the elliptical profile. This is a candidate merger remnant of intermediate age, with a surviving disk of gas and dusk aligned with the major axis.[9] This merger is estimated to have occurred 4±2.5 Gyr ago. The central part of the disk displays warping,[8] and is significantly younger than the remainder of the galaxy.[8]

The unusual amount of blue light emission of NGC 3610, or B–V in the UBV photometric system, suggests recent star formation.[9] The current estimated star formation rate is 0.385±0.375 M☉·yr−1.[4] There is a population of younger globular clusters orbiting the galaxy that is a likely product of the merger. The surviving population of older, metal-rich globular clusters suggests that at least one of the progenitor galaxies had a prominent bulge component.[9]
