NGC 2967 is a spiral galaxy in the constellation of Sextans. Its velocity with respect to the cosmic microwave background is 2,218±24 km/s, which corresponds to a Hubble distance of 106.7 ± 7.6 Mly (32.71 ± 2.32 Mpc).[1] However, five non-redshift measurements give a closer mean distance of 76.52 ± 6.16 Mly (23.460 ± 1.889 Mpc).[2] It was discovered by German-British astronomer William Herschel on 20 December 1784.[3][4]
