Near-Earth Object
Notes:

- Asteroids are divided into three classes.
- Main Asteroid Belt: First are those found in the main asteroid belt between Mars and Jupiter, which is estimated to contain somewhere between 1.1-1.9 million asteroids.
- Trojans: The second group is that of trojans, which are asteroids that share an orbit with a larger planet. NASA reports the presence of Jupiter, Neptune and Mars trojans. In 2011, they reported an Earth trojan as well.
- Near-Earth Asteroids: The third classification is Near-Earth Asteroids (NEA), which have orbits that pass close to the Earth.
