HD 108874: A Sun-Like Star and Its Two Known Planets
HD 108874 is a G5 star located 194 light-years from Earth. This makes it a Sun-like, main-sequence star, though its reported temperature of 5570 K is cooler than the Sun's. The star is older and somewhat larger than the Sun, with an age of 8 billion years, a mass of 1 solar mass, and a radius of 1.09 solar radii. Two planets are known to orbit this star.
HD 108874 b was discovered in 2002 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 451 Earth masses, a lower bound on its true mass that is larger than Earth's and roughly 1.42 times Jupiter's mass. Its orbital period is 394 days, the shortest among the listed planets by reported estimates.
HD 108874 c was discovered in 2005 by the same radial velocity method. Its minimum mass is 315 Earth masses, also larger than Earth's and the smallest minimum mass among the listed planets. It has an orbital period of 1620 days, the longest among the listed planets by reported estimates.
