NGC 1009 is a large spiral galaxy in the constellation Cetus.[1][2] Its speed relative to the cosmic microwave background is 5,594 ± 24 km/s,[3] which corresponds to a Hubble distance of 82.5 ± 5.8 Mpc (~269 million ly). NGC 1009 was discovered by American astronomer Edward Swift in 1886.[4] The luminosity class of NGC 1009 is II and it has a broad HI line.[5] To date, five non-redshift measurements yield a distance of 91.940 ± 3.045 Mpc (~300 million ly), which is just outside the distance values of Hubble.[6]
