NGC 5493 is a peculiar lenticular galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 2,929±19 km/s, which corresponds to a Hubble distance of 140.9 ± 9.9 Mly (43.20 ± 3.04 Mpc).^[1] However, three non-redshift measurements give a much closer mean distance of 64.73 ± 31.32 Mly (19.847 ± 9.602 Mpc).^[2] It was discovered by German-British astronomer William Herschel on 22 February 1787.^[3][4]

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.^[5][6]

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 NGC 5472 [fr].^[7][8]

Supernova

One supernova has been observed in NGC 5493:

• SN 1990M (Type Ia, mag. 13.5) was discovered by Robert Evans on 15 June 1990.^[9][10]
