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:

Assembled kinetic impactor for deflecting asteroids by combining the spacecraft with the launch vehicle upper stage
TL;DR: In this paper, the authors proposed the Assembled Kinetic Impactor (AKI), which combines the spacecraft with the launch vehicle upper stage to improve the deflection efficiency of the kinetic impactor strategy.

Chasing the Chelyabinsk asteroid N-body style
TL;DR: In this article, a full N-body approach was used to compute a new orbital solution with an impact probability > 0.99999 and uncertainties in time and space of 0.2 s and 6 km.

Physical characterisation of near-Earth asteroid (1620) Geographos. Reconciling radar and thermal-infrared observations
TL;DR: In this paper, the authors used the advanced thermophysical model (ATPM) on published light-curve, radar, and thermal-infrared observations to constrain the thermophysical properties of Geographos.

The Second Earth Trojan 2020 XL$_{5}$
TL;DR: In this paper, a dynamical study of asteroid 2020 XL$_5$ is presented, and it is shown that the asteroid was captured into the current Earth Trojan status in the 15th century, and then it has a likelihood of 99.5% to leave the Lagrange points of the Sun-Earth system within the next 10 kyr.
Journal ArticleDOI
Detection of Yarkovsky acceleration in the context of precovery observations and the future Gaia catalogue
TL;DR: In this article, the Yarkovsky effect is a weak non-gravitational force leading to a small variation of the semi-major axis of an asteroid using radar measurements and astrometric observations.

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).

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.
