Scientists employ various techniques to identify and track asteroids that pose a threat to Earth. They use ground-based telescopes with wide fields of view to survey the night sky, detecting objects that appear to be moving relative to the background stars. High-altitude telescopes, such as the Near-Earth Object (NEO) Surveillance Telescope (NEOST) and the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), continuously scan the sky for fast-moving objects. Artificial intelligence algorithms analyze the data to identify potential NEOs that may intersect Earth's orbit. By monitoring their trajectories and estimating their size and composition, scientists can determine which asteroids pose the greatest risk and prioritize resources for further study and potential mitigation efforts.
