Venus has the hottest surface temperature of any planet in the solar system, averaging around 900 degrees Fahrenheit (475 degrees Celsius). This extreme heat results from a thick atmosphere composed mainly of carbon dioxide, coupled with clouds of sulfuric acid, which create a strong greenhouse effect. Despite not being the closest planet to the Sun, Venus's atmosphere traps heat, making it hotter than Mercury. The high temperatures on Venus pose challenges for exploration, as spacecraft and landers must withstand harsh conditions. Understanding Venus's climate and geology provides insights into planetary processes and the potential for habitability on other worlds.
