Asteroids with similarcolors to (4) Vesta have higher albedos than the S types, and most have orbitalelements similar to known Vesta family members. The albedo distribution for asteroids with a photometrically derivedQ classification is extremely similar to those of the S types. The candidate C-typeasteroids, while generally very dark, have a tail of higher albedos that overlapsthe S types. We find a wide range of moderate to high albedos forcandidate S-type asteroids that are analogous to the S-complex defined by pre-vious spectrophotometrically-based taxonomic systems.
We have combined the NEOWISE and Sloan Digital Sky Survey data to studythe albedos of 24,353 asteroids with candidate taxonomic classifications derivedusing Sloan photometry. NEOWISE Studies of Asteroids with Sloan Photometry:Preliminary ResultsĪ. Understanding the relationship between size, albedo, and taxonomic classification is complicated by the fact that the objects with classifications were selected from the visible/near-infrared Sloan Moving Object Catalog, which is biased against fainter asteroids, including those with lower albedos. M is higher for D-type asteroids and suggest that their red visible and near-infrared spectral slope extends out to these wavelengths. Finally, we show that the relative reflectance at 3.4 and 4.6 Asteroids with similar colors to (4) Vesta have higher albedos than the S types, and most have orbital elements similar to known Vesta family members.
