HD 224693 HD 224693 (also known as ''HIP 118319'') is a metal rich〔 yellow subgiant star approximately 320 light-years away〔 in the constellation Cetus. ==Planetary system== In 2006, an extrasolar planet was discovered orbiting HD 224693 by the Keck telescope using radial velocity measurements. A preliminary search for transits using photometric data from Fairborn Observatory was inconclusive because data around the predicted time of transit was too sparse to rule out possible transits.〔
