NGC 5251 is a barred spiral galaxy in the constellation of Boötes. Its velocity with respect to the cosmic microwave background is 11202 ± 17 km/s, which corresponds to a Hubble distance of 165.22 ± 11.57 Mpc (∼539 million light-years).[1] It was discovered by German-British astronomer William Herschel on 11 April 1785.[2]

The SIMBAD database lists NGC 5251 as a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.[3]

One supernova has been observed in NGC 5251: SN 2024bci (type Ia, mag. 18.77) was discovered by the GOTO (telescope array) on 24 January 2024.[4]
