Nothing on Earth! NEO is a Near-Earth Object, which includes 3 classes
of asteroids - the Aten's stay inside Earth's orbit (but come close to
it), the Amor's stay outside Earth's orbit (but come close) and the
Apollo asteroids cross Earth's orbit. Although by some definitions it
seems the Aten's are classified as Earth-crossing asteroids with average
orbit less than Earth's, and the Apollo's Earth-crossing ones with
average orbit greater. More info at:
