NGC 632 is a lenticular galaxy in the constellation of Pisces. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . However, eight non-redshift measurements give a closer mean distance of . It was discovered by British astronomer John Herschel on 24 September 1830.
NGC 632 has a possible active galactic nucleus, 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.
NGC 632 has a nucleus which shines in the ultraviolet range, and is thus listed in Markarian's catalogue as Mrk 1002.
NGC 645 Group NGC 632 is a member of the NGC 645 group (also known as LGG 28). This group has 5 galaxies, including NGC 638, NGC 645, , and .
Supernova One supernova has been observed in NGC 632: SN 1998es (TypeIa-pec, mag. 14.6) was discovered by the Lick Observatory Supernova Search (LOSS) on 13 November 1998.
