Abstract The potentially hazardous Asteroid (101955) 1999 RQ 36 has a possibility of colliding with the Earth in the latter half of the 22nd century, well beyond the traditional 100-year time horizon for routine impact monitoring. The probabilities accumulate to a total impact probability of approximately 10 - 3 , with a pair of closely related routes to impact in 2182 comprising more than half of the total. The analysis of impact possibilities so far in the future is strongly dependent on the… Expand
Yarkovsky-driven impact risk analysis for asteroid (99942) Apophis
We assess the risk of an Earth impact for asteroid (99942) Apophis by means of a statistical analysis accounting for the uncertainty of both the orbital solution and the Yarkovsky effect. We selectExpand
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 radarExpand
Near-Earth Asteroid impact dates: A Reference Ideal Method (RIM) approach
TLDR
A novel methodology to rank the impact dates of NEAs based on the data provided by Sentry is applied, via a novel Multi-Criteria Decision Making (MCDM) method named the Reference Ideal Method (RIM). Expand
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 smallExpand

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. Expand
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 potentiallyExpand
Near Earth Asteroids with measurable Yarkovsky effect
Abstract We seek evidence of the Yarkovsky effect among Near Earth Asteroids (NEAs) by measuring the Yarkovsky-related orbital drift from the orbital fit. To prevent the occurrence of unreliableExpand
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. Expand
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 positionalExpand
Required deflection impulses as a function of time before impact for Earth-impacting asteroids
Abstract For any asteroid on an impact trajectory, the amount of time prior to impact a deflection can be implemented can drastically change the amount of deflection impulse required. In this studyExpand
