Abstract

Five-color (λλ = 0.36-0.85 μm) and thermal infrared (λ = 22.5 μm) photometric observations of the unusual asteroid 2060 Chiron were made. Between 0.36 and 0.85 μm, Chiron's reflectance spectrum is similar to those of C-class asteroids as well as Saturn's satellite Phoebe. However, the thermal IR measurements imply an albedo ≥0.05 (i.e., a diameter ≤250 km at the level 2σ level) that is probably higher than those of C-class asteroids or Phoebe.
