CoRoT7b

CoRoT-7b is an exoplanet located outside our solar system, primarily notable for being one of the first confirmed rocky planets orbiting a star other than the Sun. It was discovered by the French-led CoRoT (Convection, Rotation and planetary Transits) space telescope in 2009. The planet orbits its host star, CoRoT-7, a G-type star similar to the Sun, approximately 490 light-years away in the constellation Monoceros.

CoRoT-7b has a very close orbit, completing a revolution around its star in about 20.4 hours, classifying it as a "hot super-Earth" due to its high surface temperature. Its proximity to the star results in extreme heat, with estimated surface temperatures exceeding 1,500 degrees Celsius. The planet's mass is approximately 4.8 times that of Earth, and its radius is about 1.58 Earth radii, indicating a dense, rocky composition.

The planet's extreme environment suggests it is tidally locked, with one side perpetually facing its star, leading to significant temperature differences between the day and night sides. Its discovery was significant because it helped confirm the existence of rocky exoplanets and contributed to understanding planetary formation and composition outside of our solar system.

CoRoT-7b remains a subject of scientific interest due to its unique characteristics, providing insights into the diversity of planetary systems and the potential for rocky planets in close proximity to their host stars. Ongoing research aims to better understand its atmosphere, surface conditions, and possible geological activity, despite its hostile environment.
