Evolution of Comets Into Asteroids

In the past decade, new observations and new research tools have afforded us a better understanding of the interrelationships between comets and asteroids. The extensive automated surveys for near-Earth objects (NEOs) have serendipitously discovered many objects in comet-like orbits. Dynamical simulation codes have improved to the point where we can simulate the detailed orbital behavior of lar...

Asteroids, Comets, and Planet Formation

The solar system includes numerous small objects, generally classifiable as asteroids, comets, or interplanetary dust. Asteroids and comets are of considerable importance in the study of the terrestrial planets. The impacts of these bodies with the planets have repeatedly reshaped the planets' surfaces, redistributed the surface materials and changed their chemistry and mineralogy. In addition,...

Inelastic Dissipation in Wobbling Asteroids and Comets

Asteroids and comets dissipate energy when they rotate about any axis different from the axis of the maximal moment of inertia. We show that the most efficient internal relaxation happens at twice the frequency of the body’s precession. Therefore earlier estimates that ignore the double frequency input underestimate the internal relaxation in asteroids and comets. We suggest that the Earth’s se...

Inelastic Dissipation in Tumbling Asteroids and Comets

Asteroids and comets dissipate energy when they rotate about the axis different from the axis of the maximal moment of inertia. We show that the most efficient internal relaxation happens at the double frequency of body’s tumbling. Therefore the earlier estimates that ignore double frequency input underestimate the internal relaxation in asteroids and comets. We show that the Earth seismologica...
