How Scientists Track Near-Earth Objects

Near-Earth Objects represent a diverse population of comets and asteroids whose orbits bring them into close proximity with our planet. Tracking these bodies is vital to assess potential impact hazards and to unlock secrets about the formation of the solar system. Through a combination of ground-based facilities and spaceborne sensors, scientists have developed a multi-pronged…
