HD 15082 (also known as WASP-33) is a star located roughly 397 light years away[2] in the northern constellation of Andromeda.[10] The star is a Delta Scuti variable[11] and a planetary transit variable. A hot Jupiter type extrasolar planet, named WASP-33b or HD 15082b, orbits this star with an orbital period of 1.22 days. It is the first Delta Scuti variable known to host a planet.[12]
