NASA’s Near‐Earth Object Web Service (NeoWs), launched in 2016 as part of NASA’s planetary defense and open‐data initiatives, aggregates observations from ground‐ and space‐based telescopes to identify, track, and characterize asteroids and comets whose orbits bring them within 1.3 AU of the Sun—near Earth’s path. By publicly sharing detailed orbital parameters, size estimates (from meter‐scale rocks to 500 m behemoths like Bennu), and close‐approach statistics, NeoWs empowers researchers, educators, and citizen scientists to monitor potentially hazardous objects, model future trajectories, and develop impact mitigation strategies under the guidance of NASA’s Planetary Defense Coordination Office. Each year, surveys discover thousands of new NEOs (over 30,000 to date), most of which harmlessly pass by our planet, yet their study offers priceless insights into the solar system’s primordial materials. Monitoring their speeds—sometimes tens of thousands of kilometers per hour—and miss distances—often measured in lunar radii—underscores both the dynamism of our celestial neighborhood and the vital importance of sustained vigilance.
