Asteroid Hazard Classification for Planetary Defense

Research Project: Lightweight Machine Learning for Near-Earth Object Risk Assessment

Project Overview

Binary classifier to predict Potentially Hazardous Asteroids (PHAs) using orbital parameters, achieving planetary defense-grade accuracy while being 100x faster than deep learning approaches.

Dataset

• Source: NASA Asteroids Classification (Kaggle)
• Size: 90,836 asteroids
• Features: Absolute magnitude, diameter, velocity, miss distance, eccentricity
• Target: Binary (hazardous: 9%, non-hazardous: 91%)
