PocketCosmos

PocketCosmos employs a real-time gravitational computation engine, accurately simulating celestial motion in a SceneKit 3D environment. Technical Specifications: - Gravity formula: F = G x M x m / r2, real-time N-body simulation - Rendering: SceneKit + Metal, smooth 60fps performance - Scenarios: 8 curated astronomical simulations - Data source: Parameterized from NASA/JPL public datasets 8 Simulation Scenarios: 1. Solar System Panorama - all planets in proportional orbits 2. Inner Planets - close observation of Mercury through Mars 3. Outer Planets - Jupiter to Pluto orbital dynamics 4. Asteroid Belt - dozens of asteroid distribution simulation 5. Jupiter System - Galilean moon orbital mechanics 6. Pluto System - elliptical orbit and Charon tidal locking 7. Gravity Slingshot - probe acceleration effect demonstration 8. Solar System Top View - global perspective planetary alignment Education Module (6 topics): - Law of Universal Gravitation - Kepler's Three Laws - elliptical orbits, area law, period law - Tidal Locking - synchronous rotation mechanism - Roche Limit - critical disintegration distance - Supernova - stellar evolution final stage - Lagrange Points - three-body gravitational equilibrium Requirements: iOS 17.0+ | iPhone only Privacy: Zero data collection, fully local execution
