NGC 2442 / 2443 or commonly known as the Meathook Galaxy is an intermediate spiral galaxy about 50 million light-years away in the constellation Volans. It was discovered by Sir John Herschel on December 23, 1834.[2] Associated with this galaxy is HIPASS J0731-69, a cloud of gas devoid of any stars.[3] It is likely that the cloud was torn loose from NGC 2442 by a companion.[3]
