Abstract
THE ORIGIN OF COMETS.—In the Publikationer og mindre Meddelelser fra Kobenhavns Observatorium, No. 19, Prof. Elis Strömgren publishes a research which he has concluded with the help of Mr. J. Braae on the subject of the origin of comets. In the introduction the author refers to the results of previous workers, and suggests that the question as to whether comets came originally from interstellar space or were formed in the solar system, depends on the method of discussion adopted. The author describes fully the procedure he has used in the present research, which involves the backward computation of planetary perturbations for eight comets, and gives the numerical calculations. He is thus led to form the conclusions that there is not one warranted hyperbolic orbit among the comets of the solar system, and that all the comets yet observed have their origin in the solar system.
