   1 maj 2023 · The Near-Earth Object Program coordinates NASA-sponsored efforts to detect, track and characterize potentially hazardous asteroids and comets that could approach the Earth. Stay up-to-date on which asteroids and comets wander near Earth. The website shows distances that the closest asteroids and comets are to our home planet.

   Close Approaches. As they orbit the Sun, Near-Earth Objects occasionally approach close to Earth. CNEOS calculates the motion of all NEOs forwards to 2200 A.D. and backwards to 1900 A.D.,and determines the times and distances of the Earth close approaches. The results are tabulated here.

   As it scans the solar system, NEO Surveyor's sensitive infrared detectors will track the most elusive near-Earth objects. Dark asteroids and comets don't reflect much visible light, for example, but they will glow in the infrared spectrum as they’re heated by sunlight.
