HD 4313 and Its Planet
HD 4313 is a G-type star 445 light-years away. It is 1.72 billion years old, with a mass of 1.71 solar masses, a radius of 4.38 solar radii, and a temperature of 5010 K. Its mass and radius are larger than the Sun's, while its temperature is cooler.
One planet orbits this host. HD 4313 b was discovered in 2009 by radial velocity, the method that detects the wobble a planet's gravity induces in its star. The planet has a minimum mass of 612 Earth masses, a lower bound on its true mass, larger than Earth's and roughly 1.93 times Jupiter's mass. Its orbital period is 356 days.
