HD 216437 and Its Planet
HD 216437 is a G2/3IV star 87.1 light-years away. It is 7.16 billion years old, with a mass of 1.12 solar masses, a radius of 1.48 solar radii, and a temperature of 5850 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter. One planet orbits this host.
HD 216437 b was discovered in 2002 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. The planet's mass is 1330 Earth masses, larger than Earth's and roughly 4.2 times Jupiter's mass. Its orbital period is 1360 days.
