NGC 3117 is an elliptical galaxy in the constellation of Sextans. Its velocity with respect to the cosmic microwave background is 7,127±25 km/s, which corresponds to a Hubble distance of 342.9 ± 24.0 Mly (105.12 ± 7.37 Mpc).[1] Additionally, one non-redshift measurement gives a similar distance of 332.68 Mly (102.000 Mpc).[2] It was discovered by French astronomer Édouard Stephan on 15 March 1877.[4]
