The planet with the most extreme temperatures in the solar system is Venus. Due to its thick atmosphere, composed mainly of carbon dioxide, and extensive cloud cover of sulfuric acid, Venus experiences a strong greenhouse effect that traps heat. This causes surface temperatures to soar to around 900 degrees Fahrenheit (475 degrees Celsius), making it even hotter than Mercury, despite being further from the Sun. The extreme heat and high-pressure environment of Venus create conditions inhospitable to life as we know it, and studies of its atmosphere aid in understanding climate phenomena both on Venus and Earth.
