HD 220466 is an F-type main sequence star in the constellation Aquarius. It has apparent magnitude 6.5 and is about 212 light-years away.

In 1913, an apparent visual companion of apparent magnitude 10.3 was observed 1.9 arcseconds away from the star,[9] but it is doubtful whether it exists.[10]

The 17th-magnitude red dwarf UCAC4 342-200228 Script error: No such module "val". away from HD 220466 forms a common proper motion pairing.[4][11] Any orbit would take tens of thousands of years.[11]
