The Potentially Dangerous Asteroid (101955) Bennu
We computed impact solutions of the potentially dangerous asteroid (101955) Bennu based on 569 optical observations from September 11.40624 UTC, 1999 to January 20.11189 UTC, 2013, and 29 radar
Hazardous asteroid mitigation: campaign planning and credibility analysis
Of all the natural hazards that could befall on Earth, only an Earth impact of a large comet or asteroid has the potential to wipe out the entire civilisation in a single event while that of a small

TLDR
Keyhole maps are described as a tool to go beyond strongly scattering encounters and how to account for nongravitational perturbations, especially the Yarkovsky effect, when their contribution is the main source of prediction uncertainty.
THE ORIGIN OF ASTEROID 101955 (1999 RQ36)
Near-Earth asteroid (NEA) 101955 (1999 RQ36; henceforth RQ36) is especially accessible to spacecraft and is the primary target of NASA's OSIRIS-REx sample return mission; it is also a potentially
Near-Earth object hazardous impact: A Multi-Criteria Decision Making approach
TLDR
This work proposes the first Multi-Criteria Decision Making (MCDM) approach to classify hazardous NEOs, which allows the classification of NEOs by descending order of their TOPSIS ratio, a single quantity that contains all the relevant information for each object.
Detecting the Yarkovsky effect with the Gaia mission: list of the most promising candidates
The European Space Agency astrometric Gaia mission, due for a launch in late 2012, will observe a large number of asteroids (>250000 to V = 20mag) over five years with an unprecedented positional

Orbit determination for Near-Earth Asteroids presents unique technical challenges due to the imperative of early detection and careful assessment of the risk posed by specific Earth close approaches.

The Yarkovsky effect is a subtle nongravitational phenomenon related to the anisotropic thermal emission of Solar System objects. Its importance has been recently demonstrated in relation to the

Abstract If for an asteroid which has been observed only over a short arc and then lost there are orbits compatible with the observations resulting in collisions, recovery would be desirable to

Close approaches of asteroid 1999 AN10: resonant and non-resonant returns
The Earth passes very close to the orbit of the asteroid 1999 AN10 twice per year, but whether or not this asteroid can have a close approach depends upon the timing of its passage across the
