NGC 4168

NGC 4168 is an elliptical galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 2,609±24 km/s, which corresponds to a Hubble distance of 125.5 ± 8.9 Mly (38.48 ± 2.72 Mpc).^[1] However, 13 non-redshift measurements give a closer mean distance of 98.35 ± 10.89 Mly (30.154 ± 3.338 Mpc).^[2] It was discovered by German-British astronomer William Herschel on 8 April 1784.^[3]

NGC 4168 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.^[4][5]
