INTRODUCTION The close flyby of the Kuiper Belt object (486958) Arrokoth (formerly 2014
MU69) by NASA's New Horizons spacecraft revealed details of the body's structure, geology …

Context. Apart from a few targets that were directly imaged by spacecraft, remote sensing
techniques are the main source of information about the basic physical properties of …

The Yarkovsky effect describes a small but significant force that affects the orbital motion of
meteoroids and asteroids smaller than $30-40$ kilometers in diameter. It is caused by …

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 unreliable …

Abstract Near-Earth Asteroids (NEAs) have garnered ever increasing attention over the past
few years due to the insights they offer into Solar System formation and evolution, the …

Radiation recoil (YORP) torques are shown to be extremely sensitive to small-scale surface
topography, using numerical simulations. Starting from a set of “base objects” representative …

Context. Near-Earth asteroid (25143) Itokawa was visited by the Hayabusa spacecraft in
2005, resulting in a highly detailed shape and surface topography model. This model has …

It is now becoming widely accepted that photon recoil forces from the asymmetric reflection
and thermal re-radiation of absorbed sunlight are, together with collisions and gravitational …

Asteroid 25143 Itokawa is a small elongated asteroid with two distinct parts. The evolution of
this two-part body has been the source of speculation. The scenarios for the formation of this …

Hayabusa was the first asteroid sample return mission. It was launched in May 2003, and
arrived at the target asteroid (25143) Itokawa in September 2005. The mission enabled us to …
