HD 25723 and Its Planet

HD 25723 is a K1 III star 374 light-years from Earth. It is estimated to be 0.95 billion years old, with a mass of 2.12 solar masses and a radius of 13.8 solar radii. Its temperature is 4770 K, cooler than the Sun's. One planet orbits this host.

That planet, HD 25723 b, was discovered in 2020 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. HD 25723 b has a minimum mass of 795 Earth masses, a lower bound on its true mass, and an orbital period of 457 days. Its minimum mass is larger than Earth's and roughly 2.5 times Jupiter's mass.
