CoRoT-18b is a transiting hot Jupiter exoplanet found by the CoRoT space telescope in 2011.
[3][4] It 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.
A 2021 study 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°.
