Planet turns the solar system into something you can hold, spin, and poke at. Built for curious minds of all ages, it trades walls of text for things you can actually touch: drag through the orbits, tap a world to open it up, and see the real numbers behind it. EXPLORE THE SOLAR SYSTEM Pinch to zoom and drag to pan across the planets in their orbits. Tap any planet β€” or the Sun β€” to open its details: diameter, distance from the Sun, day length, and a short description. Then open it as an interactive 3D model you can turn in your hands. BROWSE AND SEARCH Every planet, the Sun, 20 notable moons, and a full overview of the solar system itself β€” how it formed, what's in it, and where we sit in the Milky Way. Search across all of it: type "Olympus" and you'll land on Mars. MOONS Titan's lakes of liquid methane. Enceladus firing geysers of water into space. Io, the most volcanic world we know. Ganymede, bigger than Mercury. Triton, orbiting backwards because Neptune caught it. COMPARE Put two worlds side by side and watch the scale land. Diameter, distance, day length, year length, gravity, and moons β€” drawn to their true relative size. Line Earth up against the Sun and see what 109 times wider actually looks like. TEST YOURSELF 135 questions, ten per round, drawn fresh every time. Every answer comes with a one-line explanation of why it's right, so a wrong guess teaches you something. Miss a few and you'll get them back at the end, with the reasons, to review. WEIGH IN, ANYWHERE Enter your weight and see what you'd weigh on every other planet β€” in kilograms or pounds. Enter your age and find out how many laps of the Sun you'd have made on Mars, or Neptune. SEE THEM IN 3D Load a detailed 3D model of any planet, spin it, and get close. ENGLISH AND PERSIAN Fully translated, including every article and quiz question. Switch language any time in Settings. No accounts. No ads. No data collected. Just the solar system.
