Venus: Geological and Atmospheric Features

Venus, our closest planetary neighbor, is a world of extremes with a dense, toxic atmosphere and a surface temperature reaching 900°F. Despite its harsh conditions, Venus holds clues to planetary evolution and climate change. Its unique retrograde rotation and long day-night cycle contribute to its mystique. Historical and geological studies suggest Venus may have once harbored oceans. Future missions aim to uncover more secrets, offering insights into planetary climates and the delicate balance needed for life.
