We’ve scoured the entire universe to find you a whole solar system of facts about space! If you like planets, rockets, chocolate, and cheesy jokes you will like this list of 30 Amazing Facts About Space and the Universe! So buckle up and enjoy your flight to Planet Fact!

1. Space is quieter than a librarian’s fart.

In other words it’s completely silent. There’s no atmosphere in space so there’s no way for sound to travel.

2. Uranus is the coldest planet in the solar system even though it’s not the furthest from the sun.

Chill out! We know it sounds unlikely but here comes the science bit: It’s because Uranus doesn’t have a hot core. The surface temperature is -197.2 °C. Now that’s what we call cool!

3. Mars is named after the Roman god of war

Actually, most of the planets are named after Roman gods or goddesses. Neptune is named after the Roman god of the sea and Venus was the Roman goddess of love and beauty!

4. Satellites travel at 18,000 miles per hour

It means the can orbit the earth 14 times in a single day, helping people stay in touch, find out where they are and watch netflix all at the same time!

5. Astronauts wear nappies

When they’re on a space walk astronauts wear large, absorbent underpants called a Maximum Absorption Garment. Basically a nappy then.

6. Neptune is the furthest planet from the sun

Neptune also has an atmosphere made entirely of methane the same gas that is present in cow farts. Both of these facts make it a rubbish holiday destination!

7. Venus is the hottest planet… 

...Even though Mercury is closer to the sun.

This is because Mercury has no atmosphere. Venus traps heat in its atmosphere and can reach temperatures of up to 450° C. Remember to pack your shades!

8. There is life on Mars

NASA have found what might be fossils of microscopic living creatures in mars rock.

9. In 1976 the spacecraft landed on Mars 

They were called the Viking Landers. Nice peaceful name.

10. NASA doesn’t stand for North American Space Agency

NASA stands for National Aeronautics and Space Administration

11. Uranus orbits the sun on its side.

Most planets orbit the sun like spinning tops but Uranus tilts the other way and rotates like a ball as it travels around the sun!

12. Mars is known as the red planet.

It’s red because of the large quantities of iron. Basically, the same stuff that makes our blood red too.

13. There are exactly 69450450645396432123 stars in space.

Actually that’s a guess. Nobody (not even the brainiest scientist) knows how many stars are in space but...

14. Space boffins have made a guess

The number of stars is estimated to be between 200 - 600 billion in the Milky Way (our galaxy) alone. Only a 400 billion range there, Space Boffins. Please try harder!

15. Mars has two moons

They’re called Phobos and Deimos.

16. Halley’s Comet won’t be seen until 2061

Earth’s most famous comet (and harbinger of doom to King Harold) won’t reappear until 2061!

17. We can’t get you a NASA space suit for your birthday.

They are way to expensive and cost around $12 Million.

18. There are diamonds in the sky

Yale University scholars think that the distant planet 55 Cancri e may have a surface covered in graphite and diamonds. Great news if you happen to have a space rocket or really like pencils. 

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

It turns out Venus orbits the sun faster than it rotates! It’s enough to make your head spin!

20. Our galaxy (the Milky Way) is about to collide with another galaxy causing untold chaos. 

Luckily this won’t happen for another 35 million years

21. If two pieces of the same type of metal touch in space they bond to become a single piece.

It’s called cold welding and after we found this out we spent approximately 3 hours watching cold welding videos on YouTube instead of researching space facts. Please don’t tell the Beano editor.

22. There is a huge cloud of water in space.

10 billion light years away is a massive cloud of water vapour about 140 trillion times the mass of water in the Earth’s oceans.

23. The largest asteroid is 600 miles wide

It’s so big that sometimes it’s referred to as a Dwarf Planet!

24. The Moon and the Earth are chips off the same block.

Something big hit a planet and broke off a little bit that then started to orbit the big bit. Eventually life formed on the big bit and started calling the little bit “The Moon” and the big bit “The Earth”

25. The highest mountain in the solar system is on Mars.

It’s called Olympus Mons!

26. Lots of chocolate bars are named after space things.

There’s Mars bars, Milky Ways and Galaxy chocolate. This fact was researched by our Chocolate Fact Team and probably shouldn’t have made it onto this list.

27. Space is older than a very, very old person!

Scientists have worked out that the universe is about 13.8 BILLION years old. There isn't a cake big enough to hold that many candles. It would be pretty dangerous, anyway.

28. The sun is absolutely massive!

The sun is about 864,938 miles wide, which means you could put about ONE MILLION earths inside. Don't think about this fact too much or it might hurt your mind.

29. There's a reason the Olympics are held on Earth...

Well, it's organised by humans, for a start. Some planets aren't ideal for holding sporting events. Saturn and Jupiter are made mostly of hydrogen and helium, while Neptune and Uranus have icy surfaces. You'd just have athletes slipping around and stuff. This fact was bought to you by the same person who researched the chocolate bar fact. Let’s just say they are not very sciencey.

30. A day on Pluto lasts a bit longer than one on Earth

Pluto rotates much more slowly than Earth, so one day is the equivalent of 6.4 days here. Just be glad that you don't have to go to a school there. A term at, um, Pluto High School would feel like forever!
