HD 89839 and Its Lone Known Planet

HD 89839 is an F7 V star 187 light-years away, and one planet has been found orbiting it. The star is a main-sequence dwarf somewhat hotter and larger than the Sun, with a spectral class indicating a surface temperature of 6320 K. Its mass is 1.24 solar masses and its radius is 1.29 solar radii, both larger than the Sun's corresponding values.

The planet, HD 89839 b, was discovered in 2023 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 1200 Earth masses, a lower bound on its true mass, and it completes one orbit every 3390 days. That minimum mass is roughly 3.77 times Jupiter's mass and is larger than Earth's.
