HD 149143 and Its Planet
HD 149143 is a G0 star located 239 light-years away. It is estimated to be 4 billion years old, with a mass of 1.21 solar masses, a radius of 1.49 solar radii, and a temperature of 5880 K. The star's reported mass and radius estimates are larger than the Sun's, and its temperature is hotter than the Sun's.
One planet is known to orbit this star. HD 149143 b was discovered in 2005 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion through repeated observations that reveal the planet and its orbital period. The planet has a minimum mass of 423 Earth masses, a lower bound on its true mass, and an orbital period of 4.07 days. Its minimum mass is larger than Earth's and roughly 1.33 times Jupiter's mass.
