About this page
Space Explorer shows the Sun and the eight planets moving around it. The planets are not drawn to scale, because real distances and sizes would not fit on a screen. Each planet has a short fact card with its place from the Sun, its size, its moons and one surprising fact, for example that Venus is the hottest planet and that Saturn would float in water. The space quiz asks questions at beginner, intermediate and advanced levels. Facts are kept simple and accurate for children aged about six and older.
Frequently asked questions
Do children need an account?
No. Nothing needs a login. Stars and badges are saved only on this device.
Is anything collected about my child?
No. Kids Corner does not ask for names, ages, photos or contact details, and it has no chat, no adverts and no analytics.
Are the planets to scale?
No. They are drawn bigger and closer together so you can see them all.
Why do the moon numbers say more than?
Scientists keep finding new moons, so the exact numbers change. We say more than a number that is always true.
