55 Cancri e orbits a Sun-like K-type star 41 light-years away, with a radius of 1.9 × Earth. Its ultra-short 18-hour orbit creates extreme temperatures, potentially forming molten surfaces. As a classic hot super-Earth, it contrasts temperate worlds and reveals volcanic geology. It remains a dramatic fixture in the Galactic Codex, illustrating the fiery extremes of planetary environments.
