People can vote to name a new planet!

Planet Shaogal? Or planet Delwyn? What do you think of these names?

They're just some of the options the public can choose from to call an exoplanet.

It's part of a competition by the International Astronomical Union to celebrate its 100th anniversary.

Last month, hundreds of UK schools submitted ideas for the planet name, which have now been cut down to a top ten list by a team of astronomy experts.

What is an exoplanet?

All of the planets in our solar system orbit around the Sun. Planets that orbit around other stars are called exoplanets.

WASP-13b is a large, gaseous planet which takes just four days to orbit its sun, WASP-13.

This star is more than 740 light years from Earth and is similar to the Sun, although it is likely to be larger, hotter and older.

What names have made the top ten list?

1. Snowdon and Ben Nevis (31st Burnley Guide Unit, Burnley)

These are mountains in the UK that reach up from our country towards the skies.

2. Shaogal and Breagha (379 Squadron RAF Air Cadets, Highlands)

Both these names come from the Scottish Gaelic language where Shaogal is the word for "world" while Breagha means "beautiful".

3. Delwyn and Ceridwen (Maesycwmmer Primary School, Caerphilly)

In Welsh, Delwyn means "godly friend" while Ceridwen was the Celtic goddess of rebirth, transformation, and inspiration.

4. Finlaggan and Dunyvaig (3rd Argyll, Scout Group, Argyll and Bute)

Historic ancient monuments on the Isle of Islay, Finlaggan was the ancient seat of the Norse/Gaelic Lord of the Isles and Dunyvaig was the naval fortress.

5. Elan and Galloway (Garrett Hall Primary School, Tyldesley)

These are Dark Sky Parks and some of the best areas in the UK to view the night sky.

6. Cruinlagh and Gloas (Cronk y Berry Primary School, Isle of Man)

In Manx Gaelic, Gloas means "shine" while Cruinlagh means "orbit", describing what the exoplanet and star are actually doing.

7. Dalla and Kann (Treviglas Academy, Newquay)

Kann is Cornish for "bright" while Dalla is Cornish for "beginning" and so the star and exoplanet together would be "Bright Beginning".

8. Thistle and Poppy (Mytchett Primary School, Camberley)

Using the theme of UK flowering plants, the poppy gives us hope for a peaceful future while the thistle stands for bravery, determination and strength.

9. Hafal and Recorde (Bryn Celynnog Comprehensive School, Pontypridd)

Robert Recorde was a famous Welsh mathematician who invented the equals sign which is "Hafal" in Welsh.

10. Bluestone and Sarsen (Chelmsford Hospital School, Chelmsford)

These are the two main types of rock used in the construction of Stonehenge, drawing attention to the bridge between the ancient and modern world.
