Consideration is given to the origin of organic compound-containing dust particles in Comet Halley, detected by the Puma dust impact mass-spectrometer on the Vega spacecraft. Calculations of the cometary dust temperature and data on the thermostability of organic compounds are discussed. The differences between the mineral content of cometary gas and of meteorite matter and the possible survival of dust particles organic shells during the formation of the protoplanetary disk are examined. It is suggested that the organic compounds in the dust component of Comet Halley probably originated in interstellar dust. 18 refs.
