NGC 5493
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.
