    1 maj 2023 · Near-Earth Objects, or NEOs, are comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter Earth’s neighborhood.

  7. Near-Earth objects are asteroids and comets with orbits that bring them to within 120 million miles (195 million kilometers) of the Sun, which means they can circulate through the Earth’s orbital neighborhood. Most near-Earth objects are asteroids that range in size from about 10 feet (a few meters) to nearly 25 miles (40 kilometers) across.
