HD 70642 and Its Single Known Planet
HD 70642 is a star 95.5 light-years away with one known planet. Its spectral type, G8/K1(III+F/G), places it in a temperature class sharing the G and K letters. The star is 6.24 billion years old, holds 1 solar masses, and has a radius of 1.02 solar radii - larger than the Sun's - and a temperature of 5710 K, cooler than the Sun's.
The planet HD 70642 b was found in 2003 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 633 Earth masses, a lower bound on its true mass, roughly 1.99 times Jupiter's mass. It completes one orbit every 2120 days.
