How to play Solar System Quiz
Solar System Quiz sets a turning orrery beside every question. Some questions are about the orrery itself — which planet is circled, or which one comes next as you move outward from the Sun — and the rest come from a bank of facts about the planets, their moons and the Sun.
Every answer, right or wrong, is followed by a one-line explanation, and when the answer is a planet the orrery circles it, so the facts attach to a place rather than floating free. The facts are chosen to stay true: sizes, orders, rotations and records rather than moon counts that change every few years.
There are three rounds of eight questions: the planets and their order, well-known facts, and then moons, rotations and the less obvious records. A wrong answer costs one of three hearts, and a quick right answer scores extra.
