Ways to use this list
- Space lesson starter: spin a planet and the class calls out its place from the Sun, its colour, or whether it has rings or moons.
- Put them in order: set Rank everyone for a random order of all eight, then challenge the class to rearrange them from the Sun outwards.
- Science fiction writing: spin a real planet and invent a creature that could survive there, coping with Venus's heat or Neptune's winds.
- Model solar system: with Remove the winner on, each group gets a planet and paints a ball to match its colours, bands and rings.
- Moon mission game: press Famous moons, spin a destination, and plan what your space probe should look for, from Europa's hidden ocean to Titan's lakes.
Press Spin the wheel, tap the game or press the Space bar. Change the list in the box as you
like: add your own, delete what doesn't suit you, or write *2 after an entry to give it double the
chance. The game buttons switch the same list to a duck race, hat, claw machine and more.

Questions people ask
Why is Pluto not a planet any more?
In 2006 the International Astronomical Union agreed that a planet must orbit the Sun, be round, and have cleared its path of other objects. Pluto shares its zone with many icy bodies beyond Neptune, so it became a dwarf planet.
What are the five dwarf planets?
Pluto, Ceres, Eris, Haumea and Makemake are the five officially recognised dwarf planets. Ceres lies in the asteroid belt between Mars and Jupiter; the other four orbit beyond Neptune. Astronomers think many more are waiting to be confirmed.
How can I remember the order of the planets?
Try the sentence "My Very Educated Mother Just Served Us Nachos": the first letters give Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Or make up your own; silly sentences are the easiest to remember.
Which planet is the biggest?
Jupiter, by a long way. About 11 Earths would fit across its middle, and it has more than twice the mass of all the other planets put together. The smallest planet, Mercury, is not much bigger than our Moon.
