Question
Which planet has the highest surface temperature in our
solar system?Solution
Despite Mercury being closest to the Sun, Venus is the hottest planet in our solar system with an average surface temperature of about 462°C (864°F). This extreme heat is due to Venus's dense atmosphere composed primarily of carbon dioxide, which creates a powerful greenhouse effect that traps solar radiation. Additionally, Venus has clouds containing sulfuric acid that further contribute to heat retention.
