HD 89744 and Its Planet

HD 89744 is a star 126 light-years away with a spectral type of F8 IV, placing it in the F temperature class. Its mass is 1.21 solar masses, its radius is 2.13 solar radii, and its temperature is 6250 K. Each of these stellar measurements applies to the host star itself rather than to the whole two-star system. One planet is known to orbit this star.

That planet, HD 89744 b, was discovered in 1999 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. It has a minimum mass of 2650 Earth masses, a lower bound on its true mass rather than an ordinary estimate, and it completes one orbit every 257 days. That minimum mass is larger than Earth's, and it is roughly 8.35 times Jupiter's mass.
