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. 📱 How to Use NEO Tracker 1️⃣ Install the app — No account needed 2️⃣ Browse today's asteroids or weekly schedule 3️⃣ Tap any asteroid for detailed metrics 4️⃣ View 3D orbits to visualize approaches 5️⃣ Ask the AI assistant any space question 6️⃣ Enable notifications for alerts 7️⃣ Share interesting discoveries! ❓ FAQ Is this app really free?
