Compositional Distributions and Evolutionary Processes for the Near-Earth Object Population: Results from the MIT-Hawaii Near-Earth Object Spectroscopic Survey (MITHNEOS)

•Spectra for more than 1000 near-Earth objects (NEOs) are presented and analyzed.•NEOs originate from specific regions in the main asteroid belt, according to type.•Meteorites linked to NEO classes show specific escape regions from the main belt.•Distinct spectral trends are found for surface alteration by radiation and impacts.•Altered surfaces become refreshed by planetary encounters and other processes.
