NGC 1363 is a peculiar barred spiral galaxy in the constellation of Eridanus. Its velocity with respect to the cosmic microwave background is 9,416±37 km/s, which corresponds to a Hubble distance of 453.0 ± 31.8 Mly (138.88 ± 9.75 Mpc).[1] It was discovered by American astronomer Sherburne Wesley Burnham on 31 December 1877.[2]

NGC 1363 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.[3][4]
