Origin of asteroid rotation rates in catastrophic impacts

open access: yesNature, 1997
The rotation rates of asteroids, which are deduced from periodic fluctuations in their brightnesses, are controlled by mutual collisions. The link between asteroid spin and collision history is usually made with reference to impact experiments on ...

Inelastic Collision Influencing the Rotational Dynamics of a Non-Rigid Asteroid (of Rubble Pile Type)

open access: yesMathematics, 2023
We have considered here a novel particular model for dynamics of a non-rigid asteroid rotation, assuming the added mass model instead of the concept of Viscoelastic Oblate Rotators to describe the physically reasonable response of a ‘rubble pile ...

The Apollo Group Asteroid 2008 OS9: Discovery, Orbit, Rotation and the Yarkovsky/YORP Effects

open access: yesOpen Astronomy, 2010
A project for astrometric and photometric observations of asteroids at the Baldone Observatory is described. One of the most important results of the project is the discovery of 2008 OS9, a 600 meter asteroid of the NEO Apollo group.

Optimized Asteroid Rotation and Shape Modeling through an Integrated Shape-from-silhouette and Optical Flow Approach

open access: yesThe Astronomical Journal
Asteroids offer valuable insights into the formation and evolution of the solar system. Understanding their rotation and shape is essential for studying asteroid collision histories and geological processes, as well as for planning exploration missions ...

On the Particular Dynamics of Rubble-Pile Asteroid Rotation Following Projectile Impact on the Surface During Planetary Approach

open access: yesMathematics
The main motivation of this research is the semi-analytical exploration of the dynamics of an asteroid that is attacked while approaching a planet (with an inelastic collision of the projectile normally to the surface of the asteroid occurring just ...

Averaged rotational dynamics of an asteroid in tumbling rotation under the YORP torque

open access: yesCelestial Mechanics and Dynamical Astronomy, 2010
International audienceThe secular effect of YORP torque on the rotational dynamics of an asteroid in non-principal axis rotation is studied. The general rotational equations of motion are derived and approximated with an illumination function expanded up

4963 Kanroku: Asteroid with a possible precession of rotation axis

open access: yesPlanetary and Space Science, 2018
Based on photometric observations of 4963 Kanroku as part of a campaign to measure its light-curve, changes of the light-curve profile have been detected. These changes are of a periodic nature, i.e. the profiles change with a detected period P = 16.4032

Stability of a Rotating Asteroid Housing a Space Station [PDF]

open access: yesFrontiers in Astronomy and Space Sciences, 2019
Today there are numerous studies on asteroid mining. They elaborate on selecting the right objects, prospecting missions, potential asteroid redirection, and the mining process itself.

Lightcurves, Rotation Periods, and Colors for Vera C. Rubin Observatory’s First Asteroid Discoveries

open access: yesThe Astrophysical Journal Letters
We present lightcurves, rotation periods, and colors for the first asteroid discoveries made with the NSF-DOE Vera C. Rubin Observatory. These are the first science results derived from the 2103 asteroid discoveries released as part of the Rubin First ...
