Which planet is the hottest?

The hottest planet in our solar system is Venus.
Even though Mercury is closest to the Sun, Venus is hotter than Mercury.
This is because Venus has thick clouds that trap heat very well.
Its surface temperature can reach about 900 degrees Fahrenheit!

Examples:

Imagine baking cookies in an oven; Venus acts like an oven that keeps all the heat inside.
If you could stand on Venus, it would feel like being in a sauna but much hotter.
The thick clouds on Venus make it hard for heat to escape, just like a blanket keeps you warm!

Fun Fact: Venus is so hot that if you had a metal toy on Venus, it could melt!
