Young explorers (3–6) can tap and spin planets with a grown-up. Older explorers (7–10) can read the facts, take the quizzes and play on their own. Everything is shown in English and Simplified Chinese, and you can switch at any time. Planet surfaces in the 3D explorer are illustrations made by a computer, and the explorer says clearly where sizes and distances are simplified.3至6岁的小朋友可以在大人陪伴下点一点、转一转行星；7至10岁的孩子可以自己阅读知识、做小测验和玩游戏。内容有英文和简体中文，随时可以切换。3D探索器里的行星表面是电脑画的示意图，大小和距离做了简化的地方都会清楚标明。
