Question

why Venus is hottest planet even Mercury is closest to the sun​

Answer 1

Explanation:

The thick atmosphere of Venus makes its surface hotter as the heat doesn't escape back into space. VENUS IS EVEN HOTTER THAN MERCURY THOUGH IT IS RELATIVELY FARTHER AWAY FROM THE SUN. THIS IS BECAUSE OF THE HIGH PERCENTAGE OF CARBON DIOXIDE IN IT'S ATMOSPHERE. THIS GAS TRAPS MOST OF THE SUN'S HEAT FALLING ON IT.

Answer 2

Answer:

There are some gases in Venus which make it hotter although Mercury is the closest.

I think this is the answer.
