About Solar Explorer

Solar Explorer teaches heliocentric solar system structure by challenging players to correctly sequence the eight planets from Mercury through Neptune in their actual orbital order from the Sun. The game goes beyond mere memorization by incorporating proportional orbital distances and relative planet sizes, giving players accurate spatial intuitions about the scale relationships that verbal descriptions and static diagrams fail to convey. After completing Solar Explorer, players reliably improve on solar system knowledge assessments including questions about comparative orbital periods and the asteroid belt's location relative to planetary positions.
