CoRoT-18 and Its Jupiter-Like Planet
CoRoT-18 is a star 2490 light-years away with a spectral type of G9 V. It has 0.95 solar masses and 1 solar radius, and its temperature of 5440 K is cooler than the Sun's. One planet orbits this star.
That planet, CoRoT-18 b, is a Jupiter-like world discovered by transit in 2011. Its mass is 1100 Earth masses, larger than Earth's mass and roughly 3.47 times Jupiter's mass. Its radius of 14.7 Earth radii is larger than Earth's. Its mean density is 1.92 g/cm³. CoRoT-18 b completes an orbit in 1.9 days.
