HD 47536 and Its Planet
HD 47536 is a K1 III star 400 light-years away, and one planet orbits it: HD 47536 b.
The host star is 10.2 billion years old, with a mass of 0.91 solar masses, a radius of 22.4 solar radii, and a temperature of 4420 K. Its mass is smaller than the Sun's, its radius is larger than the Sun's, and its temperature is cooler than the Sun's.
HD 47536 b was found in 2002 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Repeated wobbles reveal the planet and its orbital period. The planet's minimum mass is 2330 Earth masses, a lower bound on its true mass that is larger than Earth's and roughly 7.33 times Jupiter's mass. It completes one orbit every 712 days.
