Which Planet Is the Hottest in the Solar System?
Many assume Mercury is the hottest planet since it’s closest to the Sun. However, Venus surpasses Mercury in temperature, maintaining scorching heat due to its thick, carbon dioxide-rich atmosphere, which traps heat effectively. This phenomenon, known as the runaway greenhouse effect, keeps Venus’s surface at a consistent 465°C (869°F), making it the hottest planet in our solar system.
