      Eros' bland butterscotch colors

      These color images of Eros was acquired by NEAR on
      February 12, 2000, at a range of 1800 kilometers (1100
      miles) during the final approach imaging sequence prior
      to orbit insertion. A five and one-half hour long
      sequence of images covering visible and infrared
      wavelengths was taken at that time, to provide a global
      overview of the color and spectral properties of the
      asteroid. The images show approximately the color that
      Eros would appear to the unaided human eye.

      Eros' subtle butterscotch hue at visible wavelengths is
      nearly uniform across the surface. Two days after these
      images were taken, mapping by NEAR's infrared
      spectrometer showed that Eros exhibits a great deal more
      variety at longer wavelengths. These variations could be
      due to differences in texture or composition of the
      surface. Both NEAR's multispectral imager and infrared
      spectrometer will be used extensively during the month
      of March to map Eros' color and spectral properties from
      an altitude of 200 kilometers (120 miles). The images to
      be returned will show details as small as 20 meters (68
      feet) across, providing a new perspective on the
      asteroid's many fascinating landforms discovered so far
      by NEAR.
