CoRoT-18b is a transiting hot Jupiter exoplanet found by the CoRoT space telescope in 2011.[3]
CoRoT-18b orbits CoRoT-18 in the constellation of Monoceros. It is a G9V star with an effective temperature of 5440K, a mass of 0.95, a radius of 1.00, and a near-solar metallicity. Its age is unknown.
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°.
