Encyclopedic overview
NGC 673 is an intermediate spiral galaxy in the constellation of Aries. Its velocity with respect to the cosmic microwave background is 4894 ± 20 km/s, which corresponds to a Hubble distance of 235.4 ± 16.5 Mly (72.18 ± 5.06 Mpc). In addition, 31 non redshift measurements give a closer distance of 206.09 ± 5.54 Mly (63.187 ± 1.699 Mpc). The galaxy was discovered by German-British astronomer William Herschel on 4 September 1786.
According to A.M. Garcia, NGC 673 is the namesake of the NGC 673 Group (also known as LGG 31). This group contains at least 17 galaxies, including IC 156 [fr], IC 162 [fr], NGC 665, NGC 677, NGC 683 [fr], and 11 galaxies from the UGC catalogue.
