NGC 5493 is a peculiar lenticular galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . However, three non-redshift measurements give a much closer mean distance of . It was discovered by German-British astronomer William Herschel on 22 February 1787.
NGC 5493 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 5427 group According to A. M. Garcia, NGC 5493 is a member of the NGC 5427 group (also known as LGG 374). This galaxy group has at least four other members, including NGC 5426, NGC 5427, NGC 5468, and .
Supernova One supernova has been observed in NGC 5493: SN 1990M (TypeIa, mag. 13.5) was discovered by Robert Evans on 15 June 1990.
