CoRoT was a space telescope mission which operated from 2006 to 2013. The mission's two objectives were to search for extrasolar planets with short orbital periods, particularly those of large terrestrial size, and to perform asteroseismology by measuring solar-like oscillations in stars. The mission was led by the French Space Agency (CNES) in conjunction with the European Space Agency (ESA) and other international partners.
A super-Jupiter is a gas giant exoplanet that is more massive than the planet Jupiter. For example, companions at the planet–brown dwarf borderline have been called super-Jupiters, such as around the star Kappa Andromedae.
Chthonian planets are a hypothetical class of celestial objects resulting from the stripping away of a gas giant's hydrogen and helium atmosphere and outer layers, which is called hydrodynamic escape. Such atmospheric stripping is a likely result of proximity to a star. The remaining rocky or metallic core would resemble a terrestrial planet in many respects.

CoRoT-7b is an exoplanet orbiting the star CoRoT-7 in the constellation of Monoceros, 489 light-years from Earth. It was first detected photometrically by the French-led CoRoT mission and reported in February 2009. Until the announcement of Kepler-10b in January 2011, it was the smallest exoplanet to have its diameter measured, at 1.58 times that of the Earth and the first potential extrasolar terrestrial planet to be found. The exoplanet has a very short orbital period, revolving around its host star in about 20 hours.
CoRoT-13b is a transiting exoplanet found by the CoRoT space telescope on 12 July 2010.
Kepler-37b is an exoplanet orbiting the star Kepler-37 in the constellation Lyra. As of February 2013, it is the smallest planet discovered around a main-sequence star, with a radius slightly greater than that of the Moon and slightly smaller than that of Mercury. The measurements do not constrain its mass, but masses above a few times that of the Moon give unphysically high densities.
HD 219134 b is one of at least five exoplanets orbiting HD 219134, a main-sequence star in the constellation of Cassiopeia. HD 219134 b has a size of about 1.6 R🜨, and a density of 6.4 g/cm3 and orbits at 21.25 light-years away. The exoplanet was initially detected by the instrument HARPS-N of the Italian Telescopio Nazionale Galileo via the radial velocity method and subsequently observed by the Spitzer telescope as transiting in front of its star. The exoplanet has a mass of about 4.5 times that of Earth and orbits its host star every three days. In 2017, it was found that the planet likely hosts an atmosphere.
TRAPPIST-1f, also designated as 2MASS J23062928-0502285 f, is an exoplanet, likely rocky, orbiting within the habitable zone around the ultracool dwarf star TRAPPIST-1, located 40.7 light-years away from Earth in the constellation of Aquarius. The exoplanet was found by using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured.
K2-141b is a massive rocky exoplanet orbiting extremely close to a K Type orange main-sequence star K2-141. The planet was first discovered by the Kepler space telescope during its K2 “Second Light” mission and later observed by the HARPS-N spectrograph. It is classified as an ultra-short period planet (USP) and is confirmed to be terrestrial in nature. Its high density implies a massive iron core taking up between 30% and 50% of the planet's total mass.
CoRoT-21b is a transiting exoplanet reportedly found by the CoRoT space telescope in 2011. Planetary parameters were published in 2012.
CoRoT-11b is a transiting Hot Jupiter-sized exoplanet found by the CoRoT space telescope in 2010. From obtained light curves and Bayesian inference on the data, it is highly likely that CoRoT-11b has been observed in a secondary eclipse around its host star.
CoRoT-12b is a transiting Hot Jupiter-sized exoplanet found by the CoRoT space telescope in 2010.
CoRoT-14b is a transiting Hot Jupiter exoplanet found by the CoRoT space telescope in 2010.
CoRoT-18b is a transiting hot Jupiter exoplanet found by the CoRoT space telescope in 2011. It orbits CoRoT-18 in the constellation of Monoceros. It is a G9V star with an effective temperature of 5,440 K, a mass of 0.95 M☉, a radius of 1.00 R☉, and a near-solar metallicity. Its age is unknown. 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°.
CoRoT-20 is a star, which is located in the constellation Monoceros at a distance of about 4011 light years from the Earth. The star is orbited by at least two planets.
CoRoT-27b is a gas giant exoplanet that orbits a G-type star. Its mass is 10.39 Jupiters, it takes 3.6 days to complete one orbit of its star, and is 0.0476 AU from its star. Its discovery was announced in 2014.
