Encyclopedic overview
NGC 424 is a spiral galaxy in the constellation of Sculptor. Its velocity with respect to the cosmic microwave background is 3,303±18 km/s, which corresponds to a Hubble distance of 158.9 ± 11.2 Mly (48.72 ± 3.42 Mpc). Also, two non-redshift measurements give a similar mean distance of 165.36 ± 24.14 Mly (50.700 ± 7.400 Mpc). It was discovered by British astronomer John Herschel on November 30, 1837.
NGC 424 is a Seyfert I 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.
