摘要：

The recently discovered outer Solar System object, (5145) 1992 AD, in a somewhat Chiron-like orbit, has colors far redder than any other known asteroids or comets, and represents a hitherto-unknown spectral class. The red color may be associated with exposure of organics that are purer or more pristine than those found on the surfaces of C, P, and D asteroids, and comets, and such materials are likely to show diagnostic spectral features in the infrared. © 1992.
