IRAS Minor Planet Survey

The Minor Planet Survey supplements the asteroid data given in the Asteroid and Comet Survey; comets are not included in IMPS. All asteroids with reasonably-well-known orbits as of December 1990 are covered. In particular, IMPS updates the processing of asteroids numbered 1 through 3318, extends this processing to asteroid number 4679 and to 2,632 additional asteroids with preliminary (two or more opposition) orbits. IMPS processed only IRAS survey observations; Low-Resolution Spectrometer, Serendipitous, and Additional Observations data were not processed. This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.
