TYC 3318-01333-1 b: A Massive Planet Around a Distant Star

TYC 3318-01333-1 is a star located 1600 light-years away, and it hosts one known planet. The star is more massive than the Sun, with a reported mass estimate of 1.19 solar masses, and it is also larger, with a radius of 5.9 solar radii. Its temperature of 4780 K is cooler than the Sun's.

The planet TYC 3318-01333-1 b was discovered in 2018 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. This planet's minimum mass is 1090 Earth masses, a lower bound on its true mass, and it is roughly 3.42 times Jupiter's mass. It completes one orbit, or year, every 562 days.
