The SPACEWATCH® FMO Project, run by the University of Arizona's Lunar and Planetary Laboratory, documents the detection of Fast Moving Objects, which are near-Earth asteroids passing so close that they appear as light trails in telescope imagery. The site explains the science behind close-approach asteroid detection, shares discovery images, and describes the citizen participation program that once helped identify faint FMOs.
