HD 114783 and Its Two Planets

HD 114783 is a K1V star, a K-type main-sequence dwarf, located 68.7 light-years from the Sun. It is 6.76 billion years old, with a mass of 0.85 solar masses, a radius of 0.81 solar radii, and a temperature of 5140 K. Its mass, radius, and temperature estimates are all smaller, smaller, and cooler than the Sun's, respectively. Two planets are known to orbit this star.

Both planets were found by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. HD 114783 b was discovered in 2001, with a minimum mass of 350 Earth masses and an orbital period of 494 days. Its minimum mass is larger than Earth's and roughly 1.1 times Jupiter's mass. HD 114783 c was discovered in 2016, with a mass of 604 Earth masses and an orbital period of 4350 days. Its reported mass estimate is larger than Earth's and roughly 1.9 times Jupiter's mass. Among the listed planets, HD 114783 b has the shortest year by reported estimates, at 494 days, while HD 114783 c has the longest, at 4350 days.
