NGC 5061

NGC5061 is an elliptical galaxy in the constellation of Hydra. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . However, 25 non-redshift measurements give a closer mean distance of . It was discovered by German-British astronomer William Herschel on 28 March 1786.

NGC5061 is a Seyfert II galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.
