which planet is the hottest in the solar system
You canât tell the temperature of a planet by just looking at it, but you could make a guess at which one is the hottest. Mars is reddish color and some people might have guessed that Mars is the hottest planet in the solar system. But just because itâs red, doesnât make it the hottest. Mercury is the planet that is closest to the sun and therefore gets more direct heat, but even it isnât the hottest. Venus is the second planet from the sun and has a temperature that is maintained at 462 degrees Celsius, no matter where you go on the planet. It is the hottest planet in the solar system. So what makes Venus hotter than Mercury? Mercury doesnât have any atmosphere, and atmosphere can hold and trap heat.
