HD 106270 and Its Lone Known Planet
HD 106270 is a G5 IV star 306 light-years from Earth with one known planet in its system. It is 4.3 billion years old, holds 1.32 solar masses, spans 2.5 solar radii, and has a temperature of 5640 K. Its reported mass and radius estimates are both larger than the Sun's, while its reported temperature is cooler than the Sun's.
The system's single planet is HD 106270 b, discovered in 2011 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. It has a minimum mass of 3220 Earth masses and an orbital period of 1890 days. That minimum mass is larger than Earth's and roughly 10.1 times Jupiter's mass.
