Johann Elert Bode, another German astronomer, born in 1747 and living to 1826, had propounded a mathematical formula known as Bode's Law, which led those who accepted it to the belief that a planet would be found in what is now known as the asteroidal space.
M. de Freycinet's study of the problem they present has, however, led him to the conclusion that they existed ab origine, thus testifying rather to the preventive than to the perturbing power of the giant planet. The existence, too, of numerous asteroidal pairs travelling in approximately coincident tracks, must date from a remote antiquity.
Harding's "Celestial Atlas," designed for the special purpose of facilitating asteroidal research, was the first systematic attempt to represent to the eye the telescopic aspect of the heavens.
Yet the recognition in Eros of an "Algol asteroid" seems on other grounds inadmissible; nor until the phenomenon is conspicuously renewed as it probably will be at the opposition of 1903 can there be much hope of finding its appropriate rationale. The crowd of orbits disclosed by asteroidal detections invites attentive study.
The forces which produced this difference in the period of rotation may have contended for the mastery in that part of our solar system where the asteroids are found; and the disruption may have resulted from such conflict of forces. Or again, it may be that a large planet is now in process of formation in the asteroidal space.
Hence, in the infinite number of these changes and combinations in the countless collocations of molecules and chemically changed conditions of matter, we have the possibilities of all terrestrial life-manifestations, as we have, in the infinite number of cosmical changes, the possibilities of all planetary, cometary, and asteroidal manifestations.
Once for all, then, as the result of the star-fall of 1833, the study of luminous meteors became an integral part of astronomy. Their membership of the solar system was no longer a theory or a conjecture it was an established fact. The discovery might be compared to, if it did not transcend in importance, that of the asteroidal group. "C'est un nouveau monde planétaire," Arago wrote, "qui commence
Simon Newcomb was directed to the solution of this question, and he arrived at the conclusion that the planetary perturbations could not explain the actual situation of the asteroidal orbits. But afterward it was pointed out that the difficulty could be avoided by supposing that not one but a series of explosions had produced the asteroids as they now are.
Ku Sui had wrenched from the asteroidal belt between Mars and Jupiter and built into a world of his own, swinging it through space as he willed, and cloaking it with invisibility to baffle those who marveled at how he came and went, unseen, on his various errands. This was the mighty rock fortress in which lay the key-stone of his mounting power.
The detection of new members of the solar system has come to be one of the most ordinary of astronomical events. Since 1846 no single year has passed without bringing its tribute of asteroidal discovery.
