NGC{{nbsp}}2672 is a elliptical galaxy in the constellation of Cancer. Its velocity with respect to the cosmic microwave background is {{val|4611|21|u=km/s|fmt=commas}}, which corresponds to a Hubble distance of {{convert|68.01 ± 4.77|Mpc|Mly|abbr=on|lk=on|order=flip}}.{{r|ned}} Additionally, 11 non-redshift measurements give a distance of {{convert|57.927 ± 6.045|Mpc|Mly|abbr=on|lk=off|order=flip}}.{{cite web | url = https://ned.ipac.caltech.edu/cgi-bin/nDistance?name=NGC+2672 | title = Distance Results for NGC{{nbsp}}2672 | website = NASA/IPAC EXTRAGALACTIC DATABASE | publisher = NASA | access-date = 19 December 2024}} It was discovered by German-British astronomer William Herschel on 14 March 1784.{{cite web | url = https://cseligman.com/text/atlas/ngc26a.htm#2672 | title = New General Catalogue Objects: NGC{{nbsp}}2672| last = Seligman | first = Courtney | website = Celestial Atlas | access-date = 19 December 2024}}

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. {{cite simbad | title=NGC 2672 | access-date=18 December 2024}}

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.{{cite journal | bibcode=1937AnLun...6....1H | title=A Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems | last1=Holmberg | first1=Erik | journal=Annals of the Observatory of Lund | date=1937 | volume=6 | page=1 }} These two galaxies are also listed in Halton Arp's Atlas of Peculiar Galaxies as Arp{{nbsp}}167, with the description "Comp. galaxy very condensed, has curved plume."{{cite journal | bibcode=1966ApJS...14....1A | title=Atlas of Peculiar Galaxies | last1=Arp | first1=Halton | journal=The Astrophysical Journal Supplement Series | date=1966 | volume=14 |page=1 | doi=10.1086/190147}} Another study indicates that the two galaxies are interacting and NGC 2673 has two tidal plumes, while NGC 2672 is only weakly disturbed.{{cite journal | bibcode=1989ApJ...336..655B |title=Interacting Binary Galaxies.

Observation

One supernova has been observed in NGC 2672: SN{{nbsp}}1938B (type unknown, mag. 15.5) was discovered by Arno Wachmann in 1938.{{cite web | website=Transient Name Server | title=SN{{nbsp}}1938B | url=https://www.wis-tns.org/object/1938B | publisher = IAU | access-date=19 December 2024}}

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.{{cite book |date=2002 |first=Jan |last=Meeus |chapter=Occultations of deep-sky objects during a total lunar eclipse |pages=157–162 |title=More Mathematical Astronomy Morsels |publisher=Willmann-Bell |isbn=0943396743 |url=https://falakmu.id/khgt/dokumen/More%20mathematical%20astronomy%20morsels%20(Jean%20Meeus)%20(Z-Library).pdf}}{{rp|160}}
