Encyclopedic overview

NGC 809 is a lenticular galaxy located in the constellation Cetus about 245 million light-years (75 Mpc) away from the Milky Way. It was discovered by the American astronomer Lewis Swift in November 1886. The galaxy is receding from the Milky Way with a line of sight velocity component of 5,292 km/s.

The morphological classification of NGC 809 is (R)S0+:, indicating an outer ring structure (R) around a lenticular galaxy (S0). The galaxy has a miniature central bar structure with weakly-developed spiral arms. There is a very red ring structure that is likely dust rich. This symmetrical ring was probably formed by the impact of a satellite on the central part of the galaxy.
