HD 114783 is a star with two exoplanetary companions in the equatorial constellation of Virgo. With an apparent visual magnitude of 7.56[1] it is too faint to be visible with the unaided eye, but is an easy target for binoculars. Based on parallax measurements, it is located at a distance of Script error: No such module "convert". from the Sun, but is drifting closer with a radial velocity of −12 km/s.[2]
This is an orange-hued K-type main-sequence star with a stellar classification of K1V.[3] It is roughly 2.5[5] billion years old and is chromospherically inactive[4] with a low projected rotational velocity of 1.9 km/s.[5] The star has 88% of the mass and 81% of the radius of the Sun.[5] It is radiating 42%[6] of the luminosity of the Sun from its photosphere at an effective temperature of 5,114 K.[5]
In 2001, the California and Carnegie Planet Search team found an exoplanet, HD 114783 b, orbiting the star using the radial velocity method. The discovery was made with the Keck Telescope.[4] A second companion, HD 114783 c, was discovered in 2016,[7] and in 2023 its inclination and true mass were measured via astrometry.[8]
