Rotational force produced by sunlight may help explain the movement of small asteroids, unusual asteroid orbits, and asteroid pairs. 

Anticipating Formation Trends of Binary and Multiple Asteroids in the Main Asteroid Belt Due to Electric Discharge Effects by Using the relation of the Sun's Activity and Binary Asteroids Aggregation Statistics

Asteroids are classified as tiny and light objects in the solar system, however some of them possess orbiting moons. According to surveys, 15% of near-earth asteroids have moons. The Electrical



Rotational bursting of small celestial bodies: Effects of radiation pressure

Solar radiation pressure can cause rotational bursting and eventual elimination from the solar system of small nonmagnetic bodies in space by a sort of windmill effect. A time to bursting of about

The vector alignments of asteroid spins by thermal torques

It is shown that thermal torques are more important than collisions in changing the spin states (and possibly shapes) of asteroids with diameters <40 km, and that in some cases, the asteroids become trapped in spin-orbit resonances.

Acceleration of the rotation of asteroid 1862 Apollo by radiation torques

A change in the rotation rate of the asteroid 1862 Apollo is reported, which is fairly large and clearly visible in photometric lightcurves, confirming the prediction that the YORP effect plays a significant part in the dynamical evolution of asteroids.

Rotational bursting of interplanetary dust particles

Solar radiation pressure can cause rotational bursting and eventual elimination from the solar system of small asymmetric interplanetary particles by a windmill effect. The life span determined by

Direct Detection of the Asteroidal YORP Effect

The Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect is believed to alter the spin states of small bodies in the solar system. However, evidence for the effect has so far been indirect. We report

Radiative Spin-up and Spin-down of Small Asteroids

The Yarkovsky–O'Keefe–Radzievskii–Paddack (YORP) effect may spin up or spin down 5-km-radius asteroids on a 108-year timescale. Smaller asteroids spin up or down even faster due to the radius-squared

Spin Rate of Asteroid (54509) 2000 PH5 Increasing Due to the YORP Effect

The detection of asteroid spin-up supports the YORP effect as an explanation for the anomalous distribution of spin rates for asteroids under 10 kilometers in diameter and as a binary formation mechanism.

THE YARKOVSKY AND YORP EFFECTS: Implications for Asteroid Dynamics

The Yarkovsky and YORP (Yarkovsky-O’Keefe-Radzievskii-Paddack) effects are thermal radiation forces and torques that cause small objects to undergo semimajor axis drift and spin vector modifications,

Tektites and their origin

Questions concerning the tektite distribution are examined, taking into account the Australasian strewn field, the Ivory Coast strewn field, the Moldavite strewn field, the North American strewn

I. O. Yarkovsky and the Discovery of ‘His’ Effect

Ivan Osipovich Yarkovsky (1844-1902, see Figure 1) was a Polish civil engineer working in Russia. By day, he was employed by the Alexandrovsk railway company Moscow-Brest. In his spare time, however,
