HD 66141 and Its Single Known Planet
HD 66141 is a K2 III star located 222 light-years away. It has 1.1 solar masses and 21.4 solar radii, making its reported radius estimate larger than the Sun's. Its temperature of 4320 K is cooler than the Sun's, and its age is 6.84 billion years. One planet is known to orbit this host.
That planet is HD 66141 b, discovered in 2012 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 1910 Earth masses, a lower bound on its true mass and roughly 6 times Jupiter's mass. Its minimum mass is also larger than Earth's. HD 66141 b completes an orbit every 481 days.
