HD 102956 and Its Single Known Planet
HD 102956 is a G-type star located 398 light-years away. Its reported mass is a lower limit of 1.68 solar masses, and its radius is 4.4 solar radii, larger than the Sun's. The star's reported temperature of 5050 K is cooler than the Sun's. Its age carries a reported upper limit of 2.3 billion years.
One planet is known to orbit this host: HD 102956 b, discovered in 2010 by the radial velocity method, which detects the wobble a planet's gravity induces in its star. The planet's minimum mass is 305 Earth masses, larger than Earth's, and it completes an orbit in 6.49 days.
