摘要: Eight comets, two transition objects (extinct comet candidates), and near-Earth asteroids were imaged in four infrared bands with the SPIRIT III instrument on Midcourse Space Experiment, namely, C/1996 B2 (Hyakutake), C/1995 O1 (Hale-Bopp), Q1 (Tabur), 126P/IRAS, 22P/Kopff, 46P/Wirtanen, (3200) Phaethon, (4015) 107P/Wilson-Harrington, (4179) Toutatis, (4197) 1982 TA, 125P/Spacewatch, 55P/Tempel-Tuttle. We present maps of each object detected a description their characteristics. Five comets had extended dust tails, all which show evidence for silicate emission 8.3 μm band. The C/Hyakutake strong secondary tail along direction comet's motion, dynamical models showed was consistent from large particles. trail P/Kopff more than 2° coma three is probably composed particles emitted during 1996 apparition.
