Polarimetric properties of the lunar surface and its interpretation: Part 7 - Other solar system objects.
Optical reflection polarimetry shows that Mercury, Mars, the moon, and Callisto (for its leading hemisphere relative to its orbital motion) retain impact-blasted fragments to form a regolithic layer of fines. The following hemisphere of Callisto is found to have a consolidated surface clean of dust. The asteroids and the Mars satellites retain only a thin coating of debris. Asteroids that are polarimetrically dark are most probably enriched in carbon or Fe, while the polarimetrically light bodies are apparently of silicaceous composition. Exceptionally, asteroid 21 Lutetia belongs in the group with a regolith of fines.
