Gl 725 B is an M3.5V star, a small, cool red dwarf, located 22.3 light-years from us. One planet is known to orbit it. The star is 8.7 billion years old, with 0.25 solar masses, 0.28 solar radii, and a temperature of 3380 K. Each of these figures places it below the Sun: less massive, smaller, and cooler.
The planet is Gl 725 B c, found by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion, in 2026. Its minimum mass is 3.4 Earth masses, larger than Earth's, and its orbital period is 37.9 days. The minimum mass is a lower bound on the planet's true mass.
