💡 Planets — Fun Facts

Neptune is the farthest planet from the Sun.

It is so far away that it looks like a small blue dot. Sunlight is very weak and cold way out there.

Mercury is the smallest planet in our solar system.

It is only a little bigger than our Moon. All eight planets circle the Sun, and Mercury is the tiniest one.

Saturn's rings are made of ice and rock.

The rings are millions of icy chunks, some tiny and some big. They circle around Saturn like a giant hoop.

Uranus spins on its side, like a ball rolling along.

Most planets spin upright, but Uranus lies down as it turns. It is a pretty blue-green colour from far away.

Earth is the only planet we know of where things live.

Our planet has air to breathe and water to drink. That is why plants, animals, and people can all live here.

Mars is called the Red Planet because of its rusty dust.

The whole ground on Mars is covered in reddish-orange dust. That is why it looks like a little red dot in our night sky.

Mercury is the planet closest to the Sun.

It zooms around the Sun faster than any other planet. Up close, the Sun would look huge and very bright from Mercury.

Scientists think it rains diamonds inside Neptune and Uranus.

Deep down, huge pressure squeezes carbon into tiny diamonds that sink like rain.

Mars has a volcano three times taller than Mount Everest.

Olympus Mons stands about 22 km high — the biggest volcano in the whole solar system.

One year on Neptune lasts about 165 Earth years.

Neptune is so far from the Sun that it takes about 165 Earth years to travel around it just once. Since it was discovered in 1846, it has completed only one full orbit (finished in 2011).

Mars is home to the tallest volcano in the Solar System, called Olympus Mons.

Olympus Mons is about three times taller than Mount Everest — roughly 22 km high — and nearly as wide as the whole country of Italy. Mars looks red because its soil is full of rusty iron.

Saturn is so light for its size that it would float in water.

Saturn is made mostly of gas, so it's less dense than water — if you had a bathtub big enough, Saturn would float in it. It's also famous for its bright rings, made of countless pieces of ice and rock.

Jupiter is the largest planet in our Solar System.

Jupiter is so huge that all the other planets could fit inside it together. Its famous Great Red Spot is a swirling storm bigger than the whole Earth that has been going for hundreds of years.

A day on Venus is longer than a whole year on Venus.

Venus spins very slowly — one full turn (a day) takes about 243 Earth days, while one trip around the Sun (a year) takes about 225 Earth days. So a single day on Venus lasts longer than its year.
