HD 141937 and Its Planet
HD 141937 is a G0 star 109 light-years away with a single known planet. The star has 1.1 solar masses, 0.95 solar radii, and a temperature of 5840 K, hotter than the Sun's. Its age carries a reported upper limit of 1 billion years.
The planet HD 141937 b was found in 2002 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. The planet's mass estimate is 3590 Earth masses, larger than Earth's and roughly 11.3 times Jupiter's mass. HD 141937 b completes one orbit in 662 days.
