HD 94771 and Its Lone Known Planet

HD 94771 is a G-type dwarf 188 light-years away. Its spectral type is G3/G5 V. The star is estimated to be 5.73 billion years old, with a mass of 1.2 solar masses, a radius of 1.9 solar radii, and a temperature of 5630 K. One planet is known to orbit this host.

That planet is HD 94771 b, discovered in 2023 by the radial velocity method, which detects the wobble a planet's gravity induces in its star. The planet has a minimum mass of 169 Earth masses and an orbital period of 2160 days.

HD 94771 b's minimum mass is larger than Earth's. The star's reported mass and radius estimates are larger than the Sun's, while its reported temperature is cooler than the Sun's.
