Planet Picker Wheel — Randomly Select a Solar System Planet for Space Education
The Planet Picker Wheel spins through the eight planets of our solar system and lands on one at random — Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, or Neptune. Every planet is a world of its own, with a different size, atmosphere, day length, moon count, and distance from the Sun, so each spin opens a fresh direction for a study project, a trivia round, or a class discussion.
Because the wheel is fully editable, you can shape it to any lesson or interest. Add the dwarf planets (Pluto, Eris, Ceres, Haumea, Makemake) for a broader solar-system unit, drop in famous exoplanets like TRAPPIST-1e or Kepler-452b for advanced astronomy, or narrow it to just the rocky worlds or the gas giants. Whatever list you build, the result is decided by a cryptographically fair random draw — no planet is ever favoured. Add moons, comets, dwarf planets and the Sun to build a full solar-system unit, or connect planetary science with chemistry using the Element Picker.
The 8 Planets on the Wheel
Here is what makes each world on the default wheel distinct — a quick reference for trivia answers or for deciding which planet to research first. Astronomers group the eight into two families.
Terrestrial (inner) planets
- Mercury — the smallest planet and the closest to the Sun; a cratered, airless world where surface temperatures swing from about 430 °C in daylight to −180 °C at night.
- Venus — Earth's near-twin in size, but wrapped in a crushing carbon-dioxide atmosphere that traps heat and makes it the hottest planet of all.
- Earth — the only known world with liquid surface water and life, orbited by one large Moon.
- Mars — the "Red Planet," home to Olympus Mons (the tallest volcano in the solar system) and the target of most modern robotic missions.
Gas & ice giants (outer) planets
- Jupiter — the largest planet by far, a gas giant with a centuries-old storm (the Great Red Spot) and more than 90 known moons.
- Saturn — famous for its bright, wide ring system; a gas giant so low in density it would float in water.
- Uranus — an ice giant tipped almost completely on its side, giving it extreme seasons that each last about 20 Earth years.
- Neptune — the farthest planet from the Sun, a deep-blue ice giant with the fastest winds ever measured in the solar system.
