The IRAS Asteroid and Comet Survey is the largest, most uniform
and least biased survey ever conducted of asteroids and comets.
Because the emission observed is thermal, the present survey is not
plagued by the albedo bias to which visible wavelength analogues are
susceptible. Asteroids and comets are bright infrared sources,
particularly at 25 microns.
The IRAS hours and weeks-confirmation strategy was developed to discriminate against moving sources. However, to provide data for the study of the properties of known and newly-discovered asteroids, all sources with infrared colors typical of Solar system objects were recorded in auxiliary files at both seconds and hours-confirmation, with an emphasis on completeness.
In addition to data for 25 comets and 1811 known asteroids, a search for sources moving across the sky more rapidly than about 1' per hour resulted in the discovery of six new comets, an extensive cometary debris trail, and two Apollo asteroids, one of which may be an extinct cometary nucleus. Asteroids and comets moving more slowly than 1' per hour would hours-confirm and thus reside in the Working Survey Database.
Thirteen Asteroid and Comet data products were generated, of which four - the IRAS Asteroid Catalog, the Asteroid Statistics Catalog, the Low-Resolution Spectrometer Spectra of Selected Asteroids, and the IRAS Comet Catalog - are bound together with the Asteroid and Comet Explanatory Supplement and a User's Guide to the data products (see reference). The complete set of data products is listed in Table 8-1 of that volume. The NSSDC holds seven data products:
This catalog is available on the ADC Selected Astronomical Catalogs, Volume 2 CD-ROM and via the ADC FTP server. Supplementary asteroid data are provided in the Minor Planet Survey Database.
