CoRoT-11 b
CoRoT-11 b Encyclopedic Information
CoRoT-11 b is a behemoth of a world that serves as a masterclass in the sheer diversity of the cosmos. Located roughly 1,800 light-years away from Earth in the constellation Serpens, this Hot Jupiter is a gas giant that defies the cozy limitations of our own solar system. It orbits its host star, CoRoT-11, at a breakneck pace, completing a full year in just under three Earth days. Its existence is a testament to the chaotic beauty of planetary formation, reminding us that the universe is far more inventive than our local neighborhood suggests.

History & Significance
The discovery of CoRoT-11 b was a triumph for the French-led CoRoT (Convection, Rotation and planetary Transits) space mission, which utilized high-precision photometry to detect the rhythmic dimming of stars as planets crossed in front of them. Announced in 2010, this world was identified during a period when astronomers were transitioning from finding easy targets to mapping the complex, high-speed planetary systems that populate our galaxy. While the planet lacks a formal mythological name, its host star resides in Serpens, the Serpent, a constellation uniquely split into two parts by Ophiuchus, reflecting the duality and complexity of the ancient sky watchers imagination.
Following its initial identification, ground-based follow-up observations were crucial in confirming the planets characteristics. Telescopes across the globe helped refine the orbital parameters and mass estimates, turning a faint dip in light data into a tangible, if unreachable, world. This collaborative effort between space-based sensors and terrestrial observatories remains the gold standard for exoplanetary science, bridging the gap between raw data and the vivid reality of a distant, scorching gas giant.
Physical Structure
CoRoT-11 b is a true titan, packing a mass approximately 2.33 times that of Jupiter into a volume that makes it slightly larger than our solar system’s king. Because it orbits so close to its parent star—a mere fraction of the distance between Mercury and the Sun—the planet is subjected to extreme tidal forces and intense stellar radiation. This proximity likely keeps the atmosphere in a state of constant, violent flux, where temperatures soar high enough to suggest a world of swirling, metallic clouds and perpetual, searing winds that circulate heat from the day side to the eternal darkness of the night side.
Beneath its bloated, gaseous exterior, CoRoT-11 b likely hosts a dense, high-pressure core composed of heavy elements and metallic hydrogen. The intense heat from the star causes the planet’s outer layers to puff up, creating a puffy or inflated radius characteristic of many Hot Jupiters. As it orbits, the planet is likely tidally locked, meaning one hemisphere is forever scorched by its host star while the other lingers in a cold, shadowed exile. This thermal imbalance creates a dynamic, high-energy environment that continues to provide astrophysicists with vital data on how gas giants evolve and survive in the perilous proximity of their suns.
