📊 What is a Near-Earth Object (NEO)?

Near-Earth Objects are asteroids and comets that orbit within 1.3 AU of the Sun. NASA tracks thousands of these objects daily. Some are classified as Potentially Hazardous Asteroids (PHAs) if they pass within 0.05 AU of Earth.

🛡️ What is NASA Sentry?

Sentry is NASA's automated collision monitoring system. It continuously scans asteroid trajectories to identify objects that could impact Earth in the next 100 years.
