Background: Near Earth Objects
Near Earth Objects are asteroids that routinely pass by the Earth in their orbit around the Sun.
There are several categories: Apollos, Atens, Comets and "Potentially Hazardous Asteroids".
Over the ages, asteroids and comets have also brought much water to Earth.
They have also brought important elements including organic molecules.
The Earth accumulates thousands of tons each year from small falling meteors which burn up in the atmosphere.
Their dust falls to earth.
