Asteroids: Spun in the sun
William F. Bottke1
Abstract
Two asteroids have been observed gradually spinning faster and faster, and the hot tip is that sunlight is the cause. If so, this could give us a handle on the dynamics and evolution of the asteroid belt in general.
"Captain, something is spinning up these asteroids, and there's no way we can stop it!" What might sound like an excerpt from a long-lost episode of Star Trek is, in fact, a pretty precise description of a genuine scientific mystery.
- William F. Bottke is in the Department of Space Studies, Southwest Research Institute, 1050 Walnut Street, Boulder, Colorado 80302, USA.
