HD 220842: A Planet-Hosting Star in the Catalog
HD 220842 is a star located 211 light-years away, and it hosts a single known planet. Its spectral type is F8, indicating a temperature class hotter than the Sun's G-type, and its reported mass is 1.08 solar masses. The star's reported radius estimate is larger than the Sun's, at 1.43 solar radii, and its temperature is 5920 K.
The one planet orbiting this star is HD 220842 b, discovered in 2016 by 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 220842 b has a minimum mass of 1010 Earth masses and an orbital period of 218 days. Its minimum mass is larger than Earth's and roughly 3.18 times Jupiter's mass.
