NGC 1198 is an elliptical galaxy in the constellation of Perseus. Its velocity with respect to the cosmic microwave background is 1419 ± 14 km/s, which corresponds to a Hubble distance of 20.92 ± 1.48 Mpc (~68 million light-years).[1] It was discovered by French astronomer Édouard Stephan on 6 December 1880. This galaxy was also observed by the American astronomer Lewis Swift on 27 October 1888, and was later added to the Index Catalogue as IC 282.[2]
