HD 73534 and Its Planet
HD 73534 is a G5 star 272 light-years away. It is 4.01 billion years old, with a mass of 1.31 solar masses, a radius of 2.79 solar radii, and a temperature of 4960 K. Its reported mass and radius estimates are larger than the Sun's, while its reported temperature is cooler. One planet orbits this host.
That planet, HD 73534 b, was found in 2008 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 353 Earth masses, a lower bound on its true mass, and it completes an orbit every 1750 days. This minimum mass is larger than Earth's and roughly 1.11 times Jupiter's mass.
