NGC 1716 is a barred spiral galaxy in the constellation of Lepus. Its velocity with respect to the cosmic microwave background is 6,813±26 km/s, which corresponds to a Hubble distance of 327.7 ± 23.0 Mly (100.48 ± 7.05 Mpc).[1] It was discovered by British astronomer John Herschel on 11 December 1835.[2][3]
NGC 1716 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]
