HD 125136 b: A Planet Around a Distant Star

HD 125136 is a star 395 light-years away, with a single known planet in orbit. The star is 4.03 billion years old, has 1.55 solar masses and a radius of 5.39 solar radii, and a temperature of 4960 K. Its mass and radius are both larger than the Sun's, while its temperature is cooler.

The planet HD 125136 b was discovered in 2026 by the radial velocity method, which detects the wobble a planet's gravity induces in its star, revealing the planet and its orbital period. HD 125136 b has a minimum mass of 718 Earth masses, roughly 2.26 times Jupiter's mass and larger than Earth's. Its orbital period is 850 days, and a minimum mass is a lower bound on the planet's true mass rather than an ordinary estimate.
