The second planet from the sun in our solar system is Venus. Often referred to as Earth’s "sister planet" due to its similar size and composition, Venus has a thick atmosphere primarily composed of carbon dioxide, with clouds of sulfuric acid, making it the hottest planet in our solar system. Its surface features volcanic plains, mountain ranges, and numerous craters. Despite its harsh atmospheric conditions, Venus has been the focus of numerous space missions and continues to intrigue scientists studying planetary formation and the possibility of extreme life forms. It is also known for its bright appearance in the sky, often seen at dawn and dusk.
