HD 213240 and Its Planet
HD 213240 is a G-type star 133 light-years away. It is a main-sequence dwarf with one known planet. The star's reported mass estimate is 1.2 solar masses, larger than the Sun's, and its reported radius is 1.47 solar radii, also larger than the Sun's. Its temperature is 5920 K, hotter than the Sun's, and its age is 4 billion years. It has a companion star, making HD 213240 a two-star system.
The known planet is HD 213240 b, discovered in 2001 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 1770 Earth masses, a lower bound on its true mass, and larger than Earth's; this is roughly 5.58 times Jupiter's mass. Its orbital period is 883 days.
