HD 103891: A Single Planet Around a Hotter, Larger Star

HD 103891 is a star 181 light-years away with a spectral type of F9. It hosts one planet. The star is 3.68 billion years old and has 1.28 solar masses, 2.22 solar radii, and a temperature of 6070 K. Its mass and radius estimates are larger than the Sun's, and its temperature is hotter than the Sun's.

The planet HD 103891 b was discovered in 2022 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. The planet has a minimum mass of 458 Earth masses, a lower bound on its true mass that is larger than Earth's and roughly 1.44 times Jupiter's mass. Its orbital period is 1920 days.
