Around one ordinary star wheels a whole household: four small rocky worlds close in, four giants of gas further out, a belt of rubble between them, and comets that swing in from the cold and back out again.
The Solar System contains the Sun and the objects orbiting it: eight planets, with the four inner ones small and rocky and the four outer ones large gas giants, plus moons, asteroids in a belt between Mars and Jupiter, and comets on long elliptical orbits.
The Solar System is the Sun and everything orbiting it: eight planets, their moons, asteroids and comets.
The asteroid belt lies between Mars and Jupiter. Comets follow long, highly elliptical orbits.
Move out from the Sun past the rocky planets, the asteroid belt and the gas giants.
Four quick checks. Each correct answer earns XP and lights this skill on your star map.

The inner planets are small and rocky, the outer ones large gas giants, with a belt of asteroids between.
The asteroid belt lies between Mars and Jupiter, separating the rocky inner planets from the gas giants. Comets, unlike planets, follow very long, highly elliptical orbits rather than near-circular ones.
Unlocks once the four checks above are done. Worth more XP, written in the style of Paper 2.
