Optimization of Deflection of a Big NEO through Impact with a Small One
The Scientific World Journal, 2014 Using a small near-Earth object (NEO) to impact a larger and potentially threatening NEO has been suggested as an effective method to avert a collision with Earth. This paper develops a procedure for analysis of the technique for specific NEOs. First, an

Internal structure of Near-Earth Objects
Comptes Rendus. Physique, 2005 For the purposes of mitigation, the internal structure of near-Earth objects (NEOs) remains one of the most important but least understood parameters. From a science point of view, the internal structure is equally intriguing. Knowledge of the internal structure can reveal the collisional history, and in the case of comets, may also reveal the ...

Near-Earth Object Observations using Synthetic Tracking
Publications of the Astronomical Society of the PacificAbstract Synthetic tracking (ST) has emerged as a potent technique for observing fast-moving near-Earth objects (NEOs), offering enhanced detection sensitivity and astrometric accuracy by avoiding trailing loss. This approach also empowers small telescopes to use prolonged integration times to achieve high sensitivity for NEO surveys and
