Blast off on a mission across the solar system! Learn the order, size, and secrets of every planet as you fly from the Sun out to Neptune.
Choose your rank:
Tap the correct planet or answer (or press 1–4). Every right answer flies your rocket farther through space. Build a streak for bonus points, but watch your oxygen — three wrong answers ends the mission! The game learns what you find tricky and gives you more practice there. 🚀
