Is Venus Hottest than Mercury?

The carbon dioxide traps most of the heat from the Sun. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury.

What would happen if Mercury collided with Venus?

If Mercury were to impact Venus, even if it began by creeping up on it very, very slowly so as to have as little kinetic energy as possible, it would fall into Venus’s gravitational well and release gravitational energy enough to melt both bodies. The resulting mess would take ca.
