HD 22496 and Its Planet
HD 22496 is a K-type star 44.3 light-years away. Its spectral type, K5.0, places it in the cooler K class of stars. The star has a reported mass of 0.684 solar masses, a radius of 0.674 solar radii, and a temperature of 4390 K.
One planet is known to orbit this star. HD 22496 b was discovered in 2021 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet has a minimum mass of 5.57 Earth masses, a lower bound on its true mass, and an orbital period of 5.09 days.
The star's reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's. The minimum mass of HD 22496 b is larger than Earth's.
