Near Earth Object (NEO) NEOs include comets, asteroids, and meteors that have been affected by the gravitational attraction of nearby planets and directed into orbits that allow them to be considered “near” the Earth (i.e., within 45 million kilometers of the Earth’s orbit). NEOs are widely varied in size from centimeters to kilometers in diameter (NEO Program JPL 2015a; Abercromby et al. 2013).
