NGC 93 is an interacting spiral galaxy estimated to be about 260 million light-years away in the constellation of Andromeda. It was discovered by R. J. Mitchell in 1854.[3] The galaxy is currently interacting with NGC 90 and has some signs of interacting with it.
NGC 93 and NGC 90 form the interacting galaxy pair Arp 65.
