Question

Which is the hottest planet in our solar system.

Answer 1

HI there Friend ....

Even if Mercury is the closest planet to Sun , its is not the hottest planet.

Venus , which is the 2nd closest planet to Sun , is the hottest planet in the solar system

The atmosphere of Venus is made of mainly CO2 gas ; paving a way for green house effect.

Also , there is not atmosphere for planet Mercury

Answer 2

Hi friend

Venus is the hottest planet in the solar system.
You may think that Mercury might be the hottest planet as it's the closest to the Sun, but not at all. Venus is the hottest because of it's type of atmosphere.

Hope this helps you
