PocketCosmos

3D orbital simulation engine based on real astronomical parameters. 8 scenarios covering core celestial mechanics.

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
