How Hot Is the Planet Venus and Why Is Venus Known As the Hottest Planet In the Solar System?

The Planet Venus is very hot indeed.

The surface temperature averages almost 900°F (480°C) around the whole planet.

This extreme heat results from the greenhouse effect, which occurs when infrared, or heat-producing rays from the Sun enter an atmosphere and cannot get back out.

Carbon dioxide, which makes up 96.5 percent of Venus’s atmosphere, lets infrared rays in, but does not release them.

It absorbs the rays and radiates their heat.

The heat cannot escape into space through Venus’s crushing atmospheric pressure.

Thus, Venus has earned the title of the hottest planet in the solar system.
