CoRoT-20 and Its Two Worlds
CoRoT-20 is a G2 V star located 2750 light-years away. The spectral type places it among the Sun-like G-type dwarfs. Its age is 0.1 billion years, and it has a mass of 1.14 solar masses and a radius of 1.02 solar radii. Its temperature is 5880 K, hotter than the Sun's. Two planets are known to orbit this star.
The planet CoRoT-20 b was found by the transit method, which detects the small dip in a star's brightness when a planet crosses in front of it. Its mass is 1370 Earth masses, roughly 4.3 times Jupiter's mass, and it completes an orbit in 9.24 days.
The planet CoRoT-20 c was discovered in 2018 by the radial velocity method, which measures the wobble a planet's gravity induces in its star. Its minimum mass is 5400 Earth masses, roughly 17 times Jupiter's mass, a lower bound on its true mass. It takes 1680 days to complete one orbit.
