The Wide-field Infrared Survey Explorer will make hundreds of thousands of incidental detections of asteroids. Main belt asteroids as small as 3 km in diameter and hundreds of Near-Earth Objects (NEOs) as small as a few hundred meters in diameter will be above WISE's detection thresholds at 12 and 23 microns wavelength. Standard data products will include accurate positions and photometry for previously known solar system objects.
NEOWISE is a proposal to identify previously unknown moving object candidates and report them promptly enough to the Minor Planet Center that they can be recovered with ground-based telescopes during their discovery apparitions. The resulting consolidation of orbital elements and measurement of visual-band apparent magnitudes will enhance knowledge of asteroid diameters and enable albedos to be determined. The sampling of the NEO population by WISE will be relatively insensitive to albedo, and therefore can be used to describe the distribution of sizes of NEOs without albedo bias.
WISE's discovery tracklets of asteroids will contain 8-12 positions spanning 36 hours near the ecliptic, with better coverage at higher ecliptic latitudes. The 12 samples over 36 hours will be good for determining approximate rotation periods and IR lightcurve amplitudes.
WISE will survey on great circles at 90 deg from the sun vector, coincidentally including the "sweet spots" for discovering Potentially Hazardous Asteroids. The apparent magnitudes of NEOs when detected by WISE will run to V=21 for albedos typical of NEOs. Recovery of NEOs within 10-14 days of WISE's discoveries should not require searching more than 3 square degrees.
Another NEOWISE enhancement will enable access to the images and lists of extracted sources from the single-epoch WISE exposures. This will provide pre-discovery astrometry and physical data for solar system objects that are discovered after WISE's standard data processing is complete.
