NGC 932 is a spiral galaxy in the constellation of Aries. Its velocity with respect to the cosmic microwave background is 3,837±17 km/s, which corresponds to a Hubble distance of 184.6 ± 12.9 Mly (56.59 ± 3.97 Mpc).[1] It was discovered by German-British astronomer William Herschel on 29 November 1785.[2][3] There has been a longstanding confusion between this galaxy and NGC 930, which is a nonexistent object.[3]
