HD 56957 and Its Giant Planet

HD 56957 is a star 201 light-years from Earth with one known planet. The star has a mass of 1.03 solar masses, a radius of 1.78 solar radii, and a temperature of 5740 K. Its radius is larger than the Sun's.

The orbiting planet, HD 56957 b, was discovered in 2022 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. HD 56957 b has a mass of 1880 Earth masses and an orbital period of 5860 days. Its mass is larger than Earth's and roughly 5.92 times Jupiter's mass.
