Detecting asteroids: more, bigger, sooner

More asteroids are being detected before they pass the Earth. We are detecting them sooner, and the bigger they are, the better our chances.

Includes all near-Earth objects (NEOs) with a close approach of less than 0.05 AU and an absolute magnitude of less than 36. Missing diameters are estimated from absolute magnitude assuming a standard 0.14 albedo.
