HD 73526 b

HD 73526 b is an extrasolar planet orbiting about 61 million miles (0.66 AU) away from its parent star.^[2] This planet is more massive than Jupiter in the Solar System, so is most likely a gas giant. Based on its orbit and the stellar luminosity, the planet probably receives insolation 61% that of Mercury. HD 73526 b is in a 2:1 orbital resonance with HD 73526 c. Every time planet b goes around its sun twice, planet c goes around once.
