Across the long arc of planetary history, Venus and Mercury offer a paired lesson in how proximity to the Sun tells only part of the story of heat. Venus, once a world of oceans and temperate skies, was undone not by closeness to its star but by the invisible architecture of its own atmosphere — a runaway greenhouse effect that locked in carbon dioxide until the planet became permanently hotter than Mercury, its sunward neighbor. The tale is not merely astronomical; it is a meditation on thresholds, feedback, and the fragility of the conditions that make a world livable.
