NEAR's Multispectral Imager (MSI) recorded over 300 images of asteroid 253 Mathilde during a flyby on June 27, 1997. Images were acquired at 0.70 ยตm at solar phase angles from 40 โข to 136 โข . These data, combined with telescopic observations at phase angles from 1 โข to 16 โข were used to derive a pho
metamorphosed materials. We observed 253 Mathilde in the region 1.25-3.35 ศm to determine its hydration state and to help define a compositional We have performed spectrophotometry of the Near-Earth context in which the NEAR data may be interpreted. ## Asteroid Rendezvous flyby target 253 Mathilde
Asteroids with very slow rotation rates, up to 100 times slower than the mean for ordinary asteroids, are clearly a statistically distinct population from the rest. The cause of such slow rotation has remained a mystery since the discovery of the population about 20 years ago. The expected distribut
