Cosmos Simulation

A realistic space travel and orbital mechanics simulator built with HTML5 Canvas and JavaScript.

Features

• Realistic Orbital Mechanics: Based on Kepler's laws with accurate gravitational physics
• Auto-Pilot System: Automatically navigate to target planets
• Stable Orbit Mode: Engage in stable circular orbits around celestial bodies using relative coordinate systems
• Solar System Exploration: Navigate through our solar system including:
  • Inner planets: Mercury, Venus, Earth (with Moon), Mars
  • Outer planets: Jupiter (with Io), Saturn, Uranus, Neptune, Pluto

Controls

• Arrow Keys / WASD: Rotate and thrust
• Space: Main thruster
• Shift: Cruise mode (high-speed travel)
• X: Emergency stop / Parking brake
• Click on planet: Engage auto-pilot or orbit

Minimap Controls

• Mouse Wheel / -/=: Zoom in/out
• 0: Reset zoom
• Click on planet: Navigate to target

How to Play

1. Open index.html in a modern web browser
2. Use controls to navigate your spacecraft
3. Click on planets to automatically travel to them
4. Engage orbit mode when you arrive at your destination

Physics

The game uses realistic orbital mechanics:

• Gravitational force: F = GM/r²
• Orbital velocity: v = √(GM/r)
• Angular velocity: ω = √(GM/r³)

Technologies Used

• HTML5 Canvas
• Vanilla JavaScript
• CSS3
