THE DEVELOPMENT OF PLANETARY COSMOGONY

Abstract

All contemporary investigators in the field of planetary cosmogony consider that the planets were formed from a cold cloud of gas and dust in the vicinity of the sun. However, the opinions of scientists differ as to the origin of the cloud itself and the process of formation of planets from it. The majority consider that the principal process in planet formation was theACCUMULATION OF COLD SOLID PARTICLES. Only the American astronomer Kuiper and Academician V. G. Fesenkov assume the disintegration of a protoplanetary cloud into large, massive protoplanets which subsequently, by decreasing their masses, became the present-day planets. In addition, all scientists except V. G. Fesenkov hold that the earth was formed as a cold body and only after its formation was heated by the accumulation of radioactively generated heat. (Author)
