Near-Earth objects

Near Earth Objects (or NEOs) are objects like asteroids, comets, meteors, and other things that come close to our planet Earth. NEOs come from other parts of the universe and are called "near" because they come close to Earth. Some NEOs can even hit Earth and cause damage. Scientists use special telescopes to see and track NEOs so they can plan and prepare just in case a big NEO might come too close to our planet.
