Distribution of the near-earth objects
Solar System Research, 2011This paper analyzes the distribution of the orbits of near-Earth minor bodies from the data on more than 7500 objects. The distribution of large near-Earth objects (NEOs) with absolute magnitudes of H < 18 is generally consistent with the earlier predictions (Bottke et al., 2002; Stuart, 2003), although we have revealed a previously undetected maximum ...

Autonomous on-board Near Earth Object detection
2015 IEEE Applied Imagery Pattern Recognition Workshop (AIPR), 2015Most large asteroid population discovery has been accomplished to date by Earth-based telescopes. It is speculated that most of the smaller Near Earth Objects (NEOs) that are less than 100 meters in diameter, whose impact can create substantial city-size damage, have not yet been discovered.

Binary Asteroids in the Near-Earth Object Population
Science, 2002Radar images of near-Earth asteroid 2000 DP107 show that it is composed of an ∼800-meter-diameter primary and an ∼300-meter-diameter secondary revolving around their common center of mass. The orbital period of 1.755 ± 0.007 days and semimajor axis of 2620 ± 160 meters constrain the total mass of the system to 4.6 ± 0.5 × 10 11

The population of near-Earth objects discovered by Spacewatch
Earth, Moon, and Planets, 1996In the past three years the Spacewatch program at the University of Arizona’s Lunar and Planetary Laboratory has discovered ~45% of the new Earth Approaching asteroids and found evidence for an unheralded population of small (~10m) objects in the inner solar system.

Dynamical evolution of near-Earth objects
An apparent discrepancy between the number of observed near-Earth objects (NEOs) with small perihelion distances (q) and the number of objects that models predict, has led to the conclusion that asteroids get destroyed at non-trivial distances from the Sun.Athanasia Toliou, Mikael Granvik

Spitzer observations of Near Earth Objects
Bulletin of the American Astronomical Society, 2017The Spitzer Space Telescope has proven to be a powerful tool to measure the diameters and albedos of Near Earth Objects. We have completed two major Spitzer NEO surveys (ExploreNEOs and NEOSurvey) and are in the middle of a culiminating third survey (NEOLegacy), with a total target list across all three programs of 2175 previously known NEOs. We report
