About Space Explorer
Space Explorer is a solar system game. Start with the Planet Parade: put Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune in order from the Sun. Then test yourself on planet facts: which is the hottest, the biggest, the red one, the one with the brightest rings?
Sun, Earth and Moon explains day and night, how long a year is, why the Moon shines, and the phases of the Moon from new moon to full moon. Rocket Missions give you clues about a mystery planet and fly you there when you guess it.
Every planet you learn about wins its space card, plus cards for the Sun and the Moon. Your progress is saved on this device.
