HD 158038 and Its Planet
HD 158038 is a K0 star located 309 light-years away. One planet orbits this host. The star is 1.98 billion years old and has a mass of 1.65 solar masses, a radius of 5 solar radii, and a temperature of 4900 K. Its mass and radius are larger than the Sun's, while its temperature is cooler.
The planet HD 158038 b was discovered in 2011 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 486 Earth masses, larger than Earth's and roughly 1.53 times Jupiter's mass. It completes one orbit every 521 days.
