Design Rationale

The Real-Time Asteroid Tracking Visualizer is designed with a focus on user engagement and educational value. The 3D visualization powered by Three.js provides an immersive experience, while React ensures a responsive and efficient user interface. The backend uses Node.js and Express for their excellent performance in handling real-time data and API requests.

PostgreSQL was chosen for its robustness in managing relational data, particularly useful for user accounts and favorites. The RESTful API architecture allows for easy scalability and potential future expansion to mobile apps.

The file structure separates concerns clearly, promoting maintainability and collaboration among developers. The deployment strategy using containerization and Kubernetes ensures scalability and ease of management as the application grows in popularity.

By combining cutting-edge web technologies with accurate astronomical data, this visualizer aims to make space exploration accessible and exciting for users of all backgrounds.
