NGC 3277 is a spiral galaxy in the constellation of Leo Minor. Its velocity with respect to the cosmic microwave background is 1,712±21 km/s, which corresponds to a Hubble distance of 82.4 ± 5.9 Mly (25.26 ± 1.80 Mpc). However, five non-redshift measurements give a much farther mean distance of 148.34 ± 17.58 Mly (45.480 ± 5.389 Mpc). It was discovered by German-British astronomer William Herschel on 11 April 1785.
NGC 3277 is a Seyfert II galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.
NGC 3254 group
NGC 3277 is a member of the NGC 3254 group (also known as LGG 197), which contains five galaxies, including NGC 3245A, NGC 3245, NGC 3254, and NGC 3265.
Supernova
One Supernova has been observed in NGC 3277:
- SN 2025coe (Type Ib-Ca-rich, mag. 17.4) was discovered by Kōichi Itagaki on 24 February 2025. Its light curves displayed multiple distinct peaks which is very rare among known calcium-rich supernovae, with only SN 2019ehk showing similar features. It had an exceptionally large projected physical offset of ~39.3 kpc (~317.7″) from the galactic center, making it the most distant multi-peaked calcium-rich supernova ever discovered relative to its host galaxy. The progenitor system might have been ejected through dynamical interactions.
