Planet HD 115954 b and Its Sun-Like Star

HD 115954 is a G0 V star, a Sun-like dwarf, located 286 light-years away. It has one known planet, HD 115954 b, discovered in 2021 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The star's reported mass is 1.18 solar masses and its radius is 1.21 solar radii, both larger than the Sun's, and its temperature of 5960 K is hotter than the Sun's.

HD 115954 b has a minimum mass of 2630 Earth masses, or roughly 8.29 times Jupiter's mass, making it more massive at minimum than Earth. It completes an orbit every 3700 days.
