Which is the hottest planet in solar system?

Answer 1

Venus is the hottest planet. Although it is only the second closest to the sun, its thick Carbon Dioxide atmosphere causes it to have a severe runaway greenhouse effect. Mercury is the closest planet to the sun, but it has no atmosphere therefore more of the suns light is reflected back out into space.
