HD 74156 b is an extrasolar planet at least 88% more massive than Jupiter that orbits very close to the star. Its surface temperatures must be high and its radius about 1.15 times that of Jupiter. It is most likely a gas giant. This planet was discovered in April 2001 by Dominique Naef and Michel Mayor along with the second planet HD 74156.
