HIP 74890 and Its Planet
HIP 74890 is a K1 III star located 257 light-years away. It is 4.41 billion years old, with a mass of 1.31 solar masses, a radius of 4.62 solar radii, and a temperature of 4820 K. Its reported mass and radius estimates are larger than the Sun's, while its reported temperature is cooler than the Sun's. One planet is known to orbit this star.
That planet, HIP 74890 b, was discovered in 2016 through 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. HIP 74890 b has a minimum mass of 763 Earth masses, larger than Earth's and roughly 2.4 times Jupiter's mass. Its orbital period is 822 days.
