NGC 3377 is an elliptical galaxy of intermediate luminosity[6] in the equatorial constellation of Leo.[1] It was discovered on April 8, 1784 by German-British astronomer William Herschel.[8] This galaxy has an apparent visual magnitude of 10.2[5] with an angular size of 5.2′ × 3.0′.[7] It is located at a distance of 37 million light-years (11.2 Mpc)[4] and has a diameter of approximately 40,000 ly.[7] NGC 3377 is a member of the M96 Group of galaxies. A very faint companion galaxy, NGC 3377A, is at an angular separation of 7.1′ to the northwest.[7]

The morphological classification of NGC 3377 is E5–6, indicating an elliptical galaxy with an elongated shape.[6] The velocity distribution shows a sharp rise within an arcsecond of the core, demonstrating the presence of a supermassive black hole.[9] This object has an estimated mass of 8.0+0.5
−0.6×107 M☉.[4] The galactic halo has a virial mass estimated at (3.6±0.6)×1011 M☉.[6] It has a system of globular clusters with an estimated 400–500 members.[10]
