WASP-76 b orbits a hot F-type star 634 light-years from Earth, an ultrahot gas giant with a radius of 20.8 × Earth. Completing an orbit every 1.81 days at 0.033 AU, it endures dayside heat high enough for iron to exist as vapor, then cool and rain toward the night side at dusk. Tidally locked and bloated, it presents a chemical gradient from day to night that charts extreme weather on a giant world. Such conditions test how atmospheres circulate, condense, and escape under relentless stellar glare. This dramatic planet endures in the Galactic Codex as a record of molten-metal skies and the violent beauty of close-in systems.
