Wolf 1069 and Its Planet

Wolf 1069 is an M5.0 V star, a small, cool red dwarf, located 31.3 light-years away. It has one known planet.

Wolf 1069 b was discovered in 2023 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. The planet has a minimum mass of 1.26 Earth masses, larger than Earth's, and an orbital period of 15.6 days.

The host star has a mass of 0.167 solar masses, a radius of 0.181 solar radii, and a temperature of 3160 K. Its mass and radius are smaller than the Sun's, and its temperature is cooler.
