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 Te = 5440K, M = 0.95M☉, R = 1.00R☉, and near-solar metallicity. Its age is unknown.
Orbit
The study in 2012, utilizing a Rossiter–McLaughlin effect, have determined the planetary orbit is probably aligned with the rotational axis of the star, misalignment equal to -10±20°.[5]
