Description
🔍 Explore
Build your own celestial system and command gravitational orbits in space. Experiment with stars, planets, and moons to see how gravity and velocity create stable orbits or cosmic collisions.
🎮 Try It
• In Intro mode, drag the planet's velocity arrow to change its initial speed and direction, then press Play.
• Turn on Paths to trace the planetary orbit and check Predict to see the future trajectory.
• In Lab mode, explore presets like Slingshot or Binary Star to watch how multiple masses tug on each other.
🎯 Your Mission
In Intro mode, adjust the planet's speed until its stretched, oval orbit becomes a smooth, near-perfect circle.
🌍 Real-World Connection
Space probes like Voyager used gravitational slingshot flybys around Jupiter and Saturn to gain speed and reach the outer solar system without using fuel.
