HD 98649 b: A Giant World Around a Sun-Like Star
HD 98649 is a G4 V star, a Sun-like dwarf, located 138 light-years away. It has one known planet. The star is 2.3 billion years old and has a mass of 1 solar masses, a radius of 1 solar radii, and a temperature of 5760 K.
The planet HD 98649 b was discovered in 2012 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its orbital period is 5380 days. Its mass is 3080 Earth masses, roughly 9.7 times Jupiter's mass and larger than Earth's.
