NGC 5630 is a barred spiral galaxy in the constellation of Boötes. Its velocity with respect to the cosmic microwave background is 2826 ± 11 km/s, which corresponds to a Hubble distance of 41.68 ± 2.92 Mpc (∼136 million light-years).[1] It was discovered by German-British astronomer William Herschel on 9 April 1787.[2]
NGC 5630 is listed as a field galaxy, i.e. one does not belong to a larger galaxy group or cluster and hence is gravitationally alone.[3]
