HD 167768 and Its Lone Known Planet

HD 167768 is a G8 III star 350 light-years away. Its reported radius estimate is larger than the Sun's, at 9.7 solar radii, while its temperature is cooler than the Sun's, at 4850 K. The star has an ordinary mass estimate of 1.08 solar masses and an age of 5.31 billion years. One planet is known to orbit it.

That planet, HD 167768 b, was discovered in 2022 by the radial velocity method and has a minimum mass of 270 Earth masses, larger than Earth's. Its orbital period is 20.7 days, so it completes one orbit in that span. The minimum mass is a lower bound on the planet's true mass; the actual mass may be higher.
