HD 72490 and Its Planet

HD 72490 is a G-type star 412 light-years away. Its spectral type of G5 places it in the same temperature class as the Sun, though the star is cooler, with a temperature of 4930 K. The star is also larger than the Sun, with a mass of 1.21 solar masses and a radius of 4.96 solar radii. One planet is known to orbit this host.

That planet is HD 72490 b, discovered in 2018 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 562 Earth masses, a lower bound on its true mass, and this is larger than Earth's and roughly 1.77 times Jupiter's mass. The planet completes an orbit every 858 days.
