UH
Astronomer Discovers Asteroids Change Color as They Age
 |
| Robert
Jedicke |
A team led by
UH Institute for Astronomy’s Robert
Jedicke provides convincing evidence that asteroids
change color as they age. A variety of methods were used to estimate
asteroid ages that range from 6 million up to 3 billion years.
Accurate color measurements for over 100,000 asteroids were obtained
and catalogued. The results were published in the May 20 issue
of Nature.
Once researchers refine their analysis by obtaining more colors of the youngest-known
asteroid surfaces, it will be possible to determine the age of any asteroid
from its surface color.

This enhanced false color image of Ida gives a vivid example of the effect
of space weathering on asteroids. By measuring the rate of space weathering
on asteroids Jedicke and his collaborators can now estimate the ages of the
various colored regions on the surface of asteroids like Ida. Photo courtesy
