HD 74156 d is a proposed exoplanet with minimum mass 40% the mass of Jupiter. If the orbital inclination is not wholly face-on to Earth, then it would be a gas giant. It orbits about the same distance as Earth to the Sun, too hot for the system's habitable zone. It was first observed by Jacob Bean and his team at the University of Texas.
