CoRoT-18b is a transiting hot Jupiter exoplanet found by the CoRoT space telescope in 2011.[3][4]
Host star
CoRoT-18b orbits CoRoT-18 in the constellation of Monoceros. It is a G9V star with an effective temperature of 5,440 K (5,170 °C; 9,330 °F), a mass of 0.95 M☉, a radius of 1.00 R☉, and a near-solar metallicity. Its age is unknown.
Orbit
The study in 2012, utilizing the Rossiter–McLaughlin effect, has determined the planetary orbit is probably aligned with the rotational axis of the star, with a misalignment equal to -10±20°.[5]
