Near-Earth Objects

Near-Earth Objects (NEOs) are space rocks—such as asteroids and comets—that come into close proximity to Earth's orbit. They vary in size from small pebbles to objects kilometers across. Because of their proximity, there’s a potential risk of collision with Earth, which could cause significant damage depending on their size and impact location. Scientists closely monitor NEOs to track their paths, predict future positions, and develop strategies for impact prevention if necessary. Understanding NEOs is essential for planetary defense and ensuring Earth's safety from potential impacts.
