Venus
Venus is the second planet from the Sun and Earth’s closest planetary neighbor, a cloud‑shrouded terrestrial world of extreme heat and pressure with a dense carbon dioxide atmosphere. Similar in size and bulk composition to Earth, it rotates retrograde, has no moons, and exhibits global cloud super‑rotation, an intense greenhouse effect, and signs of ongoing volcanism. Modern knowledge comes from decades of flybys, orbiters, landers, and atmospheric probes from multiple space agencies.
