GJ 724 b: A Nearby Planet Orbiting a Small, Cool Star

GJ 724 is a star 55.3 light-years from Earth with a spectral type of M1.0 V, making it a small, cool red dwarf. The star has a reported mass estimate of 0.527 solar masses and a radius estimate of 0.522 solar radii, both smaller than the Sun's. Its reported temperature is 3800 K, cooler than the Sun's. One planet is known to orbit this host.

That planet, GJ 724 b, was discovered in 2023 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. GJ 724 b has a minimum mass of 10.8 Earth masses, larger than Earth's, and an orbital period of 5.1 days. A minimum mass is a lower bound on a planet's true mass, distinct from an ordinary mass estimate.
