## PocketCosmos Description
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
