DX Cancri is also known as G 051-015, GJ 1111 and informally Proxima Cancri. It is a nearby red dwarf flare star designated. A "spectacular" flare was detected in 2006. A search for a dust disk was undertaken, but none was found. This is thought to be a member of the Castor Moving Group. Its proper motion may first have been noticed by William Luyten.
