HD 24064 and Its Planet

HD 24064 is a K0 star located 979 light-years away. Its measured mass is 1 solar masses, its radius is 38 solar radii, and its temperature is 4050 K. The star's reported radius estimate is larger than the Sun's, while its reported temperature is cooler than the Sun's. It is 9 billion years old. One planet is known to orbit this host.

That planet is HD 24064 b, discovered in 2015 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 24064 b has a minimum mass of 4100 Earth masses, a lower bound on its true mass that differs from an ordinary mass estimate. That minimum mass is larger than Earth's and roughly 12.9 times Jupiter's mass. The planet completes one orbit every 536 days.
