CoRoT4b

CoRoT4b is an exoplanet discovered by the CoRoT (Convection, Rotation and planetary Transits) space telescope, launched and operated by the French space agency CNES in collaboration with international partners. It was detected using the transit method, observing the dimming of its host star as the planet passes in front. CoRoT4b was announced in 2010 as part of the mission's exoplanet catalog.

CoRoT4b is classified as a hot Jupiter due to its large size and close proximity to its host star. It has a mass approximately 1.2 times that of Jupiter and a radius about 1.1 times Jupiter's. The planet orbits its star at a very short distance, completing a revolution roughly every 9.2 days. Its host star is a G-type main-sequence star similar to our Sun, located approximately 2,600 light-years from Earth in the constellation Monoceros.

The planet's characteristics suggest it is a gaseous giant with a high surface temperature, likely exceeding 1,000 degrees Celsius due to stellar irradiation. Its orbital parameters and mass provide valuable insights into planetary formation and migration theories, especially concerning close-in gas giants.

Data collected from CoRoT4b contribute to understanding the diversity of planetary systems and the dynamics of hot Jupiters. Its discovery remains significant within the broader context of exoplanet research, aiding astronomers in building statistical models of planet populations beyond our solar system. The ongoing study of CoRoT4b and similar exoplanets enhances knowledge of planetary atmospheres, compositions, and orbital behaviors in extreme environments.
