NGC 1954 is a large spiral galaxy in the constellation of Lepus. Its velocity with respect to the cosmic microwave background is 3,172 ± 4 km/s, which corresponds to a Hubble distance of 46.8 ± 3.3 Mpc Mpc (∼153 million light-years).[1] It was discovered by German-British astronomer William Herschel on 14 December 1786.
