Gl 725 A and Its Planet
Gl 725 A is an M-type dwarf star 11.5 light-years from Earth, with a spectral class that marks it as a small, cool red dwarf. It hosts one known planet. The star's mass is 0.33 solar masses, its radius is 0.351 solar radii, and its temperature is 3430 K. Its age is 6.2 billion years. Each of these measurements is smaller or cooler than the corresponding value for the Sun.
The single planet, Gl 725 A b, was discovered in 2025 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 2.78 Earth masses, larger than Earth's, and its orbital period is 11.2 days.
