Gam Psc: A Single Planet Around a Distant Star

Gam Psc is a star 135 light-years away with a spectral type of G7 III. It has 0.99 solar masses and a radius of 11.2 solar radii, which is larger than the Sun's. Its temperature is 4740 K, cooler than the Sun's. One planet orbits this host: gam Psc b.

Gam Psc b was discovered in 2021 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 426 Earth masses, larger than Earth's and roughly 1.34 times Jupiter's mass. The planet completes an orbit every 555 days.
