HD 1502 and Its Planet
HD 1502 is a K-type star 623 light-years away. It has 1.53 solar masses and 3.98 solar radii, making it more massive and larger than the Sun. Its temperature of 5010 K is cooler than the Sun's, and its age is 2.34 billion years.
One planet orbits this star. HD 1502 b was found in 2011 through the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 874 Earth masses, roughly 2.75 times Jupiter's mass and larger than Earth's, and its orbital period is 429 days.
