Brightness temperature measurements have been conducted for Jupiter, Saturn, Uranus, and Neptune, as well as the Galilean satellites Europa, Ganymede, and Callisto, and the asteroid Ceres, at 355 microns. The precise shape of the spectra of these bodies can be used to obtain information on their composition and the state of compactness of their surface/subsurface layers. The temperatures obtained for the giant planets agree with both previous measurements and model atmosphere calculations; the present result for Jupiter is noted to be consistent with a model atmosphere spectrum lacking a CH3-ice cloud, or perhaps with one having small (10-micron) particles. 12 refs.
