HIP 79431 and Its Planet

HIP 79431 is a star 47.4 light-years away, with one known planet in orbit. The host is an M3 V star, an M-type main-sequence dwarf. Its mass is 0.477 solar masses, its radius is 0.479 solar radii, and its temperature is 3420 K. Each of these values is smaller or cooler than the Sun's corresponding value.

The single planet, HIP 79431 b, was discovered in 2009 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 667 Earth masses and an orbital period of 112 days. That minimum mass is larger than Earth's and roughly 2.1 times Jupiter's mass, making it a lower bound on the planet's true mass.
