NGC 828 is a spiral galaxy in the constellation of Andromeda. Its velocity with respect to the cosmic microwave background is 5118 ± 17 km/s, which corresponds to a Hubble distance of 75.49 ± 5.29 Mpc (∼246 million light-years).[1] It was discovered by German-British astronomer William Herschel on 18 October 1786.[2]

NGC 828 is a LINER galaxy, i.e. it has a type of nucleus that is defined by its spectral line emission which has weakly ionized or neutral atoms, while the spectral line emission from strongly ionized atoms is relatively weak.[1] In addition, NGC 828 is classified as a radio galaxy.[3]
One supernova has been observed in NGC 828: SN 2024lea (type Ib, mag. 19.1).[4]
