A Full-Stack Platform for Real-Time Near-Earth Object (NEO) Monitoring
Cosmic Watch is a full-stack web application designed to monitor Near-Earth Objects (NEOs) in real time. The platform connects directly to NASA’s NeoWs API to fetch live asteroid data and transforms complex scientific information into simple, understandable risk insights.
The goal is to make space data accessible to everyone — from researchers and students to everyday users — by providing clear visualizations, intelligent risk analysis, and personalized alert systems.
- The system fetches live asteroid data from NASA.
- The backend processes and evaluates the risk level of each object.
- The frontend presents this information in a clean, interactive dashboard.
- Users can track specific asteroids and receive alerts for close approaches.
- Optional 3D visualization provides a visual representation of asteroid movement around Earth.
Cosmic Watch includes a secure account system to protect user data and enable personalized tracking.
- Secure Registration & Login — users can create an account and log in safely, similar to any modern web platform.
Passwords are never stored as plain text. They are encrypted using industry-standard hashing, ensuring database security even in case of breaches.
After login, users receive a secure digital token that verifies their identity for future requests.
Certain features such as watchlists and notifications are accessible only to authenticated users.
Each user has a personal dashboard where they can manage saved asteroids and view alerts.
The platform connects directly to NASA’s NeoWs API to retrieve up-to-date asteroid data.
The backend fetches daily asteroid information directly from NASA’s public database.
Users can view asteroids passing near Earth within a selected date range.
Each asteroid has a unique identifier. Users can access detailed information about any specific object.
For every asteroid, the platform shows:
- Estimated diameter
- Relative velocity
- Miss distance from Earth
- Close approach date
- Hazard Classification
If NASA marks an asteroid as potentially hazardous, it is clearly labeled in the interface.
To simplify complex scientific data, Cosmic Watch includes a custom-built risk evaluation system.
A mathematical formula analyzes multiple parameters and generates a risk score.
Instead of showing raw numbers, the system classifies asteroids into:
- Low Risk
- Moderate Risk
- High Risk
Evaluation Factors
Risk levels are calculated based on:
- Diameter
- Velocity
- Miss distance
- NASA hazard flag
- Dynamic Calculation
Risk is recalculated automatically whenever new data is received, ensuring up-to-date assessments.
Cosmic Watch allows users to monitor specific asteroids and receive automated alerts.
Users can add asteroids to a personal watchlist.
Users can define thresholds such as:
- Distance limits
- Days before close approach
The system runs automated background checks at regular intervals using scheduled tasks.
When alert conditions are met, users receive notifications within their dashboard.
The dashboard is designed for clarity and ease of use.
Real-time asteroid information is presented in a structured layout.
Users can:
- Sort by distance
- Sort by size
- Filter by hazard status
Risk Indicators
Color-coded badges allow users to instantly recognize risk levels.
Each asteroid has a dedicated page displaying full data and risk analysis.
All notifications are accessible from a centralized alerts section.
To enhance understanding, Cosmic Watch includes optional 3D rendering.
The application renders a simplified space environment directly in the browser.
Earth is positioned at the center for intuitive spatial understanding.
Asteroids move along simulated orbital paths, helping users visualize approach patterns.
The platform includes an optional live discussion feature.
- WebSocket-powered real-time messaging
- Live discussion threads
- Accessible only to authenticated users
This allows users to discuss specific asteroids and space events collaboratively.
