TLDR
In this article, the Yarkovsky effect among near Earth asteroids (NEAs) was investigated by measuring the YARKovsky-related orbital drift from the orbital fit using a high precision dynamical model, including the Newtonian attraction of 16 massive asteroids and the planetary relativistic terms.About:

Yarkovsky Drift Detections for 247 Near-Earth Asteroids
TL;DR: In this article, the authors analyzed both optical and radar data for 600 near-Earth asteroids (NEAs) for the purpose of detecting and quantifying the Yarkovsky effect and found that the observed ratio of negative to positive drift rates in their sample is 2.34.

Impact Probability Under Aleatory And Epistemic Uncertainties
TL;DR: In this paper, an approach to estimate an upper bound for the impact probability of a potentially hazardous asteroid when part of the force model depends on unknown parameters whose statistical distribution needs to be assumed is presented.

Impact Risk Estimation and Assessment Scales
Steve Chesley,Paul W. Chodas +1 more
TL;DR: In this article, the authors present the current state of the art in assessing the impact risk from any of the known near-Earth objects over the next century or so, by determining the orbits of potentially hazardous asteroids and comets using the latest sets of tracking measurements and then projecting into the future the possible positions for these objects during close approaches to the Earth.

Observational data and orbits of the comets discovered at the Vilnius Observatory in 1980–2006 and the case of the comet 322P
Ireneusz Włodarczyk,K. Černis +1 more
TL;DR: In this article , the authors studied the orbital evolution of comet 322P with and without non-gravitational effects, and found that many of the comet's orbital clones go into and out of retrograde orbits, sometimes repeatedly.

Theory and Experiment in Gravitational Physics
TL;DR: In this paper, the authors provide a complete treatment of techniques for analyzing gravitation theory and experience, taking into account the Dicke framework, basic criteria for the viability of a gravitation theories, experimental tests of the Einstein equivalence principle, Schiff's conjecture, and a model theory devised by Lightman and Lee (1973).

TL;DR: In this article, a best-fit model of the near-Earth objects (NEOs) population is presented, which is fit to known NEs discovered or accidentally rediscovered by Spacewatch.

THE YARKOVSKY AND YORP EFFECTS: Implications for Asteroid Dynamics
TL;DR: The Yarkovsky and YORP effects are thermal radiation forces and torques that cause small objects to undergo semimajor axis drift and spin vector modifications, respectively, as a function of their spin, orbit, and material properties as discussed by the authors.
Application of photometric models to asteroids.
TL;DR: In this paper, the brightness of a rough and porous surface is parameterized in terms of the optical properties of individual particles, by shadowing between particles, and by the way in which light is scattered among collections of particles.
