NGC 828 is a spiral galaxy in the constellation of Andromeda. Its velocity with respect to the cosmic microwave background is 5200 ± 17 km/s, which corresponds to a Hubble distance of 250.2 ± 17.5 Mly (76.70 ± 5.37 Mpc).[1] Additionally, three non-redshift measurements give a closer distance of 223.52 ± 7.06 Mly (68.533 ± 2.165 Mpc).[2] It was discovered by German-British astronomer William Herschel on 18 October 1786.[3]

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.[4]

One supernova has been observed in NGC 828: SN 2024lea (Type Ib, mag. 19.1) was discovered by the Zwicky Transient Facility on 10 June 2024.[5]
