HD 196885 A and Its Planet

HD 196885 A is an F8 V star 111 light-years away, with a reported age of 2 billion years, a mass of 1.33 solar masses, and a temperature of 6340 K. Its mass estimate is larger than the Sun's, and its reported temperature is hotter. One planet is known to orbit this host.

That planet, HD 196885 A b, was discovered in 2007 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. The planet has a minimum mass of 820 Earth masses, a lower bound on its true mass, which is roughly 2.58 times Jupiter's mass and larger than Earth's. It completes one orbit every 1330 days.
