# Solar System Simulation 🌎 🌍 🌏
A Python-based solar system simulation using PyGame that accurately models planetary orbits based on gravitational forces.
## ✨ Features
- Real-time planetary motion simulation
- Gravitational force calculations between celestial bodies
- Distance tracking from the Sun
- Orbital path visualization
- Accurate scaling of astronomical units
- Multiple planets including:
- Sun (central body)
- Mercury
- Venus
- Earth
- Mars
## 🔧 Physics Implementation
The simulation implements several key astronomical and physical concepts:
- **Gravitational Force**: Uses Newton's law of universal gravitation (G = 6.67428e-11)
- **Astronomical Unit**: Accurately scaled distances (1 AU = 149.6e6 km)
- **Velocity Calculations**: Realistic orbital velocities for each planet
- **Time Scaling**: One day per timestep (3600*24 seconds)
## 🛠️ Technical Details
### Constants
```python
AU = 149.6e6 * 1000 # Astronomical Unit in meters
G = 6.67428e-11 # Gravitational constant
SCALE = 250 / AU # Pixel scaling (1AU = 100 pixels)
TIMESTEP = 3600*24 # One day per simulation step
```
### Planet Properties
| Planet | Mass (kg) | Orbital Velocity (km/s) | Color |
|---------|------------------|------------------------|-----------|
| Sun | 1.98892 × 10^30 | - | Yellow |
| Mercury | 3.30 × 10^23 | 47.4 | Dark Grey |
| Venus | 4.8685 × 10^24 | 35.02 | White |
| Earth | 5.9742 × 10^24 | 29.783 | Blue |
| Mars | 6.39 × 10^23 | 24.077 | Red |
## 🚀 Getting Started
1. Install Python 3.x
2. Install PyGame:
```bash
pip install pygame
```
3. Clone the repository:
```bash
git clone https://github.com/yourusername/solar-system-simulation.git
cd solar-system-simulation
```
4. Run the simulation:
```bash
python solar_system.py
```
## 🎮 Controls
- Close window to exit simulation
- Simulation runs automatically once started
- Orbits are traced automatically
## 🖥️ Display Features
- 800x800 pixel window
- Planet sizes scaled for visibility
- Distance from Sun displayed in kilometers
- Orbital paths traced in planet's color
- Smooth 60 FPS animation
## 🧮 Classes and Methods
### Planet Class
- **Attributes**:
- Position (x, y)
- Radius
- Color
- Mass
- Velocity (x_vel, y_vel)
- Orbit path tracking
- **Methods**:
- `draw()`: Renders planet and orbit path
- `attraction()`: Calculates gravitational forces
- `update_position()`: Updates planet position based on forces
## 📝 Dependencies
- Python 3.x
- PyGame
- Math module (standard library)
## 🤝 Contributing
Contributions are welcome! Here are some ways you can contribute:
1. Add more planets
2. Implement additional physics calculations
3. Add interactive features

## 🌟 Future Enhancements
- Add more planets (Jupiter, Saturn, etc.)
- Include moons and their orbits
- Add planet rotation
- Implement zoom functionality
- Add time controls (speed up/slow down)
- Include planetary data display
## ⚠️ Notes
- Planet sizes are not to scale (enlarged for visibility)
- Time is accelerated for better visualization
- Orbits are simplified (not accounting for all real-world factors)
