The 1.2 to 3.5 microns observations of asteroid 4179 ToutatisThe close Earth approach of the Apollo asteroid 4179 Toutatis during the winter of 1992-1993 provided a unique opportunity for detailed ground-based observations of a near earth asteroid (NEA). Because of their relatively small size NEA's are usually far too faint to be observable by most ground-based instruments. This opposition by Toutatis was, however, exceptionally favorable. Toutatis approached within 0.03 AU of Earth and was as bright as 11th visual magnitude. This made the object observable in a wide variety of wavelengths including radar, thermal IR, near IR, and visual.
