The Cumulation of Debris Clouds around a Fast-rotating Asteroid
The Astrophysical JournalThe rotational mass loss has been realized to be a prevalent mechanism to produce low-speed debris near the asteroid, and the size composition of the asteroid’s surface regolith has been closely measured by in situ explorations.

The shape and rotation of the tumbling asteroid (99942) Apophis
, 2014 International audiencePhotometric observations of the asteroid (99942) Apophis taken from December 2012 to April 2013 revealed that it is in a non-principal axis rotation state. We constructed a numerical model of the asteroid's shape and rotation.

Rotationally Resolved Mid-infrared Spectroscopy of (16) Psyche
The Planetary Science JournalAsteroid (16) Psyche is theorized to be an exposed iron core of a primordial asteroid and is the target of the upcoming NASA Psyche mission. Recent observations of Psyche identified the presence of rotational heterogeneity, a fine-grained regolith ...

Dynamic 3D Simulation of Surface Charging on Rotating Asteroids
The Astrophysical JournalThe surface-charging phenomenon of asteroids, mainly resulting from solar wind plasma and solar radiation, has been extensively studied. However, the influence of the asteroid’s rotation on surface charging is not yet fully understood.

A Formula for the Rotation Periods of the Planets & Asteroids
, 1998 The note presents a formula for the prediction of the rotation periods of the planets and asteroids. This formula, which is like the Titius-Bode law, gives a good agreement with the rotation periods of most planets, shows that Venus is retrograde, and that there must be five objects between Mars and Jupiter.

An Earth Encounter as the Cause of Chaotic Dynamics in Binary Asteroid (35107) 1991VH
The Planetary Science JournalAmong binary asteroids, (35107) 1991VH stands out as unique given the likely chaotic rotation within its secondary component. The source of this excited dynamical state is unknown. In this work, we demonstrate that a past close encounter with Earth could
