WASP-18 b orbits an F-type star 410 light-years away, sized 11.2 × Earth (1.0 Jupiter radius) with massive heft. Its ultra-short 0.94-day orbit creates scorching conditions and strong tidal interactions. As a benchmark for decaying orbits, it offers insights into hot Jupiter migration. This dramatic entry in the Galactic Codex illustrates the dynamic fates of close-in giants, evoking the relentless forces shaping planetary systems across the stars.
