Only 267 of the 41,884 known near-Earth asteroids have had their makeup measured, and makeup is what decides what an asteroid is worth. The rest were guesses. The model predicts each one’s type from data we already have, which takes us from 267 classified to 838 and makes the list actually searchable. Value comes from size, mass and makeup. How hard each one is to reach comes from published numbers where they exist, and an estimate everywhere else.
