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

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.

Radiation Forces and Trajectory of Hayabusa2♯ Target 1998 KY26
The Astrophysical Journal LettersSmall near-Earth asteroid 1998 KY _26 has recently become an object of interest because it is the target of the Hayabusa2 ♯ mission and because challenges in fitting its astrometric data have led to classifying it as a dark comet.
