It was not only the physical nature of comets that so long remained a mystery. Their origin was also shrouded in obscurity, and the various hypotheses put forward to explain this were to some degree influenced by beliefs about their nature.

Kinematics and Physics of Celestial Bodies, 2009
The paper presents a brief history of cometary cosmogony. It discusses critically the eruptive hypothesis, the hypothesis on the relict origin of comets, and the hypothesis on a genetic connection between comets and trans-Plutonian planets. Laplace’s theoretical prediction as to the capture of long-period comets by Jupiter into short-period orbits is ...

An Interstellar Origin for Comets
1982It is usually supposed that the outer regions of the Oort cloud have been thermalised by the cumulative effect of stellar encounters and that the long-period comets are perturbed into the inner solar system by passing stars. This heating, or relaxation, is a gentle process, Weissman (1980) for example estimating that only ∿ 9% of the primordial comet ...

Originally published in 1953, this book first sets out some observational facts about comets, then the greater part of the book accounts for their origin and explains how comet tails are formed. The text contains 34 photographs of celebrated comets, including eight of Halley's comet. A comet index is also provided.
