Abstract
Statistics on near-Earth asteroids (NEAs) discovery and follow-up observations as a function of geographical location are presented. The majority of discoveries and follow up observations are made from the northern hemisphere which has the preponderance of facilities. It is suggested that because of the current dearth of observation programs in the southern hemisphere that there are some (high inclination) NEAs less likely to be discovered, tracked, and recovered. To assist in discovering these NEAs and carrying out follow-up (recovery) observations on others, both primary (discovery) and secondary (< 4-m) (follow-up) facilities should be placed in the southern hemisphere and supported by amateur observation follow-up networks. To optimally discover NEAs with orbits inferior to Earth’s, an IR observing satellite should be positioned in an inferior orbit, e.g. between Venus and Mercury. To physically characterize NEOs, additional 2- to 4-m telescopes are needed
