HD 211392 is a suspected[8] variable star in the equatorial constellation of Aquarius, positioned about 346 light-years away.[2] With an apparent magnitude close to six, according to the Bortle scale it is just visible to the naked eye from dark, rural skies. It is a giant star with a stellar classification of K3III.[3]
