HD 86081 and Its Solitary Known Planet

HD 86081 is an F8 star 339 light-years away. Stellar measurements describe the host star alone: it is 6.5 billion years old, has a mass of 1.2 solar masses and a radius of 1.49 solar radii, and a temperature of 5860 K. Its spectral type classifies it as hotter than the Sun, and its reported mass estimate and radius estimate are both larger than the Sun's. One planet is known to orbit this host.

That planet, HD 86081 b, was discovered in 2006 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. The repeated wobbles reveal the planet and its orbital period, here 2.14 days. HD 86081 b has a minimum mass of 470 Earth masses, a lower bound on its true mass that is larger than Earth's and roughly 1.48 times Jupiter's mass.
