How Does The Temperature of the Planets in Our Solar System Work?

The temperature of each planet depends on how close it is to the Sun and what kind of blanket it has around it.

Imagine the Sun is like a big, warm lamp in the sky, shining down on all the planets. The closer a planet is to this lamp, the warmer it gets. That’s why Mercury, the closest planet, can be super hot during the day, like standing right next to the lamp!

But some planets have blankets made of gases that trap heat, like a cozy sleeping bag. Venus has a thick blanket of carbon dioxide, making it really hot inside, hotter than Mercury at night!

On the other hand, Earth has just the right amount of blanket, not too thick, not too thin, so we stay comfortable.

Mars, though, is farther away from the Sun and has a thinner blanket. So it gets quite chilly, like being in a cold room with only a light blanket on.

Far out in the cold, Neptune and Uranus are like kids who forgot their blankets, they’re super chilly because they’re so far from the warm lamp of the Sun!
