Solar System Explorer
Eight planets, in order, for good
About Solar System Explorer
Drag the planets into their true order from the sun, then learn what makes each one different — moons, rings, storms and sideways spin.
Ankhdase tracks 3 distinct skills in Solar System Explorer, including Solar system, Planet order & distance and Planets, moons & rings. Because mastery is estimated per skill rather than per game, the questions shift toward whatever a student is getting wrong — and away from what they have already proved they know.
How to play
- Order from the sun: drag each planet into a numbered slot, closest to the sun on the left.
- Tap a planet then tap a slot if dragging is fiddly — both work.
- Check my order tells you how many are right without telling you which ones are wrong.
- Name that planet and Planet facts test what you learned; "Look it up" is always there if you are stuck.
Skills Solar System Explorer practices
- Solar system
- Planet order & distance
- Planets, moons & rings
Mastery is estimated separately for each of these, which is what lets the difficulty move independently — a student can be fluent on one and still be fed easier questions on another.
