Solar System Simulation
A Python-based solar system simulation using Pygame for real-time visualization of planetary orbital mechanics, gravitational interactions, and celestial physics — including accurate Newton's law computations, orbital velocity, escape velocity, and data export to CSV.
Le Défi
- Accurately simulating gravitational attraction between all planet pairs in real time
- Decomposing force vectors into x/y components for multi-body orbital paths
- Maintaining simulation stability across large time step variations
La Solution
- Implemented Newton's law of universal gravitation with full force decomposition using atan2.
- Optimized the simulation loop to iterate over all planet pairs efficiently using list comprehension.
- Added a configurable time-step parameter so users can slow down or speed up the simulation.
Fonctionnalités Clés
- Real-time gravitational force simulation between all bodies
- Accurate orbital velocity and period calculations (Kepler's 3rd Law)
- Moon and Star object support
- Escape velocity, surface gravity, and orbital period per planet
- CSV data export for all computed attributes
- Dynamic logging and error handling
