On 12 February, 2000, the NEAR spacecraft obtained a sequence of 780 images of Eros from a range of about 1800 km (1100 miles). This sequence covered one complete revolution of the asteroid at 0.5 degree intervals. In these views of opposite hemispheres of the asteroid, groups of images slightly apart in time were digitally processed to bring out local details. The processed data showing Eros from slightly different perspectives can then be combined as anaglyphs or stereo pairs. The processing of the data highlights the topography of small-scale features, but makes the gross shape of the asteroid appear flattened.

Built and managed by The Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland, NEAR was the first spacecraft launched in NASA's Discovery Program of low-cost, small-scale planetary missions. See the NEAR web page at http://near.jhuapl.edu/ for more details.
