'''HAT-P-3b''' is an [[extrasolar planet]] approximately 457 [[light-year]]s away in the [[constellation]] of [[Ursa Major]]. It was discovered by the [[HATNet Project]] via the [[astronomical transit|transit]] method, so both its mass and radius are known quite precisely; based on these figures it is predicted that the planet has about 75 [[Earth mass]]es worth of heavy elements in its core, making it similar to the planet [[HD 149026b]].<ref name="discovery"/> |
