CoRoT-2 b
CoRoT-2 b Encyclopedic Information
Imagine a world where the sun never sets, but instead, it scorches everything in its path with relentless, hellish intensity. CoRoT-2 b, a bloated gas giant located roughly 930 light-years away in the constellation Aquila, is not your typical vacation destination. As a Hot Jupiter, this exoplanet orbits its host star at a blistering pace, completing a full year in just 1.7 Earth days. It stands as a testament to the chaotic diversity of our galaxy, challenging our understanding of planetary formation and survival in the extreme proximity of a volatile parent star.

History & Significance
CoRoT-2 b earned its place in the history books in 2007, discovered by the pioneering French-led CoRoT (Convection, Rotation and planetary Transits) space mission. Using the transit method—detecting the subtle dip in starlight as the planet passed in front of its sun—astronomers realized this was no ordinary world. Unlike the tranquil planets of our own solar system, CoRoT-2 b was found to be unusually puffy, leading to intense scientific debate about how such a massive object could maintain such a large radius without being stripped away by stellar winds. While it lacks a mythological namesake from antiquity, its discovery marked a golden era in exoplanet research, proving that our space-based telescopes could peer into the depths of the Milky Way to find worlds that defy conventional physics.
Physical Structure
Physically, CoRoT-2 b is a titan of the cosmos, packing roughly 3.3 times the mass of Jupiter into a volume that makes it look like it is bursting at the seams. Scientists believe the planet’s extreme inflation is likely fueled by the intense tidal heating and X-ray radiation from its host star, CoRoT-2, which is significantly more active than our own Sun. The atmosphere is a swirling, high-temperature cauldron, likely reaching temperatures upwards of 1,500 degrees Celsius, where clouds of vaporized minerals and metals may drift through a sky that knows no darkness. Beneath its outer layers, the planet likely possesses a dense, metallic core, though the line between the atmosphere and the interior is blurred by the crushing pressures found deep within its gaseous shroud. It is a world of extremes, where the internal heat and external bombardment create a dynamic, ever-changing environment that remains one of the most enigmatic laboratories for atmospheric physics in the universe.
