Earth Facts for Kids

Earth Facts for Kids

Humans have lived on Earth for around 200,000 years, although the planet itself is much, much older than that. Although there’s still so much we don’t know about our planet, we now have a greater understanding of it than we’ve ever had.

With that in mind, we’ve gathered together 10 of the most interesting Earth facts for kids. We’ve also put together a free PDF poster of these 10 facts which you can print off and stick on the wall at home. If your kids are still eager to learn more about our amazing planet, at the bottom of the blog we’ve included links to some further reading.

10 Facts About the Earth for Kids


1. The Earth is spinning around at 1,000 mph

This is why we have daytime and nighttime. It means that one side of the planet is in light, and the other is in darkness.

2. Earth is thought to be 4.5 billion years old

And it has changed a lot over the years. Around 250 million years ago, Earth was home to one ‘supercontinent’ called Pangea. Since then, it slowly broke apart and formed the continents we know today.

3. It’s only the 5th biggest planet in our solar system

The Earth’s diametre – the distance from one side to the other – is around 12,800 km. But that’s nothing compared to Jupiter, the biggest planet in the solar system, which measures 143,000 km. Saturn, Uranus and Neptune are all also bigger than Earth.

4. The Earth takes 365.25 days to orbit the Sun

Because of the extra six hours that it takes to orbit the Sun, every four years we need to add a leap day to the calendar. This day falls on 29th February.

5. Earth has one moon and no rings

Jupiter has 79 moons, whilst Saturn has between 500 and 1,000 rings around it. Earth is the only known planet that has just one moon.

6. It’s the only ocean planet in our solar system (and possibly the universe)

Around 70% of the Earth’s surface is covered in water. It’s a big reason why Earth can support life, as it provides 70% of the planet’s oxygen.

7. It’s the only known planet that supports life

The unique conditions on Earth – when compared with other planets – mean it is capable of supporting life in many forms.

8. The Sun is 1.3 million times bigger than Earth

That’s big!

9. The Earth’s atmosphere protects it from many things

It helps to warm the planet, in an effect known as ‘The Greenhouse Effect.’ Without this, the Earth’s oceans would freeze over (and so would we!). It also protects us against meteors, which break up in the atmosphere before they can reach the surface.

10. Earth is part of a group of planets called ‘The Milky Way’

The Milky Way is one of an estimated 2 TRILLION galaxies in our universe. And it’s possible that there is more than one universe out there. Mathematically-speaking, that means there is a good chance that life exists on other planets. We just have to find it!
