HD 73526 is an extrasolar planet orbiting about 61 million miles (0.66 AU) away from its primary star. The planet is more massive than Jupiter in our solar system, so is most likely a gas giant. Based on its orbit and the stellar luminosity, the planet probably receives similar insolation to Mercury.

HD 73526 c is an extrasolar planet orbiting about 97 million miles (1.05 AU) away from its primary star. Based on its mass, this planet is likely to be a gas giant. At the distance this planet orbits from its star, which is more luminous than our Sun, HD 73526 c would receive insolation similar to Venus.

HD 73526 c is in a 2:1 orbital resonance with HD 73526 b. Every time planet b goes around its sun twice, planet c goes around once, a similar configuration to planets b and c of the Gliese 876 system.
