NGC 2672 is a elliptical galaxy in the constellation of Cancer. Its velocity with respect to the cosmic microwave background is 4,611±21 km/s, which corresponds to a Hubble distance of 221.8 ± 15.6 Mly (68.01 ± 4.77 Mpc).[1] Additionally, 11 non-redshift measurements give a closer distance of 188.93 ± 19.72 Mly (57.927 ± 6.045 Mpc).[2] It was discovered by German-British astronomer William Herschel on 14 March 1784.[3]
The SIMBAD database lists NGC 2672 as an Active Galaxy Nucleus Candidate, 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.[4]
NGC 2672 is listed with the galaxy NGC 2673 as Holm 99 in Erik Holmberg's A Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems, published in 1937.[5] These two galaxies are also listed in Halton Arp's Atlas of Peculiar Galaxies as Arp 167, with the description "Comp. galaxy very condensed, has curved plume."[6] Another study indicates that the two galaxies are interacting and NGC 2673 has two tidal plumes, while NGC 2672 is only weakly disturbed.[7]

Supernovae
Two supernovae have been observed in NGC 2672:
- SN 1938B (type unknown, mag. 15.5) was discovered by Arno Wachmann in 1938.[8]
- SN 2025yla (Type Ia-91bg-like, mag. 15.5) was discovered by the Zwicky Transient Facility on 18 January 2025.[9]
Other observations
On 29 January 1953 it was occulted by the Moon during a Total Lunar Eclipse (the January 1953 lunar eclipse) over the South Atlantic and extreme south of Africa.[10]: 160
