Many researchers consider that nes can be prolonged up to the earth incidence border that makes about 930 000 km Most often it is the area from the layers of the neutral terrestrial atmosphere. Because of encounters primarily with planets in the inner solar system, neo orbits are fundamentally unstable with an average residence time less than ten million years Neos are constantly replenished from the main asteroid belt and cometary reservoirs, primarily as a. It has long been debated whether the neos are mostly of asteroidal or cometary origin With improved knowledge of resonant dynamics, it is now clear that the asteroid belt is capable of supplying most.
Neas are likely targets for resources to support space industrialization, as they may be the least expensive source of certain needed raw materials The limited supply of precious metals and semiconducting elements on earth may be supplemented or even replaced by the reserves floating in the form of.
