HD 108341 and Its Single Known Planet

HD 108341 is a K2 V star, a class-level designation marking it as a K-type main-sequence dwarf, located 160 light-years away. Its reported mass estimate is 0.843 solar masses, its reported radius estimate is 0.79 solar radii, and its reported temperature is 5120 K. All three of these stellar measurements are smaller than the Sun's corresponding values, with the temperature also being cooler. The star is 4.9 billion years old. One planet orbits this host.

That planet is HD 108341 b, discovered in 2014 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 1110 Earth masses, meaning its true mass is at least this large; this is larger than Earth's mass and roughly 3.5 times Jupiter's mass. The planet completes one orbit every 1130 days.
