Answer:
The thickness of the ozone layer (for earth) and the atmosphere.
Mercury is the closest planet to the sun but it isn’t the hottest because it has no atmosphere. Although Venus is the second planet from the sun, it is the hottest because of it’s thick atmosphere and the clouds that trap heat in. HOPE THIS HELPS
Another factor is the thickness of the atmosphere. Mercury is closest to the sun but its temperature isn't high because it has no atmosphere. Venus on the other hand has a very thick atmosphere, so this affects its temperature a lot and it releases heat.
