Gravity solar system simulator

What hackers pick instead

• Interactive 3D three-body problem simulatorFree browser simulator for watching 3D three-body orbits, with presets and many settings people find fun. Critics note energy isn't conserved and orbits often fly apart.20recommend
• Falstad Math and Physics SimulationsA free collection of interactive math and physics simulations that run in the browser, recommended for students and anyone who wants to explore wave and physics behavior visually.6recommend
• Newton's OrchardA browser-based space and gravity playground that people say helps newcomers understand the physics through its dynamic visualization, with visuals that one commenter found on par with Stellarium.5recommend
