HD 220466 is a F-type subgiantormain sequence star in the constellation Aquarius. It has apparent magnitude 6.47 and is about 200 light-years away.[1] In 1913, an apparent visual companion of apparent magnitude 10.3 was observed 1.9 arcseconds away from the star,[7] but it is doubtful whether it exists.[8]
