GJ 9714 and Its Planet
GJ 9714 is a K5V star located 66.9 light-years away. Its spectral type places it among the cooler, orange-dwarf class of stars. The star's reported mass estimate is smaller than the Sun's, at 0.67 solar masses, and its reported radius estimate is also smaller than the Sun's, at 0.663 solar radii. Its reported temperature is cooler than the Sun's, at 4260 K.
One planet is known to orbit GJ 9714. GJ 9714 b was discovered in 2022 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. The planet's reported mass estimate is larger than Earth's, at 2990 Earth masses, and is roughly 9.4 times Jupiter's mass. Its orbital period is 19200 days.
