HD 185283 and Its Planet

HD 185283 is a K3 V star located 102 light-years away. Its spectral type identifies it as a K-type main-sequence dwarf, a class cooler and redder than the Sun's G type. The star has a reported mass estimate of 0.79 solar masses, a reported radius estimate of 0.743 solar radii, and a temperature of 4850 K. One planet is known to orbit it.

That planet, HD 185283 b, was discovered in 2023 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its mass is 413 Earth masses, making it larger than Earth and roughly 1.3 times Jupiter's mass. It completes one orbit every 4060 days.
