**Facts About Venus: What the Planet Reveals About Our Solar System** Why is Venus drawing growing attention in the US and beyond? Recent space exploration missions, combined with rising public interest in planetary science and climate studies, have reignited fascination with Earth’s “sister planet.” Venus, often called Earth’s twin due to its size and rocky composition, offers vital clues about planetary formation, atmospheric dynamics, and the delicate balance that shapes habitability—making it a key topic in modern science communication. Venus orbits the Sun every 225 Earth days, yet its surface is far from calm. Satellite radar mapping reveals a landscape dominated by vast volcanic plains, extensive impact craters, and a network of tectonic faults, hinting at a geologically active world—though unlike Earth, it lacks active plate tectonics. Surface temperatures regularly exceed 450°C (830°F), hot enough to melt lead, due to a dense atmosphere trapping heat in what scientists call a runaway greenhouse effect. Beyond geology, Venus’s atmosphere is a powerful case study in atmospheric science. Composed mostly of carbon dioxide with thick clouds of sulfuric acid, it provides a natural laboratory for understanding climate feedback loops and atmospheric chemistry. These insights inform not only planetary research but also climate modeling on Earth and beyond.
