Planet HR 5183 b: A Giant World in a Wide Orbit
HR 5183 is a G-type star 103 light-years from Earth, and one known planet orbits it. The star is 7.7 billion years old and contains 1.07 solar masses of material. Its radius is 1.53 solar radii, and its surface temperature is 5790 K.
The planet, HR 5183 b, was discovered in 2019 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet's minimum mass is 1030 Earth masses, a lower bound on its true mass, and it completes one orbit every 27000 days. Because the radial velocity method tracks these wobbles, it reveals both the planet and its orbital period.
