Abstract
MM. M. Kamień ski and R. Walter have a paper with this title (Extrait Bull, de l‘Acad. Polon. Sci. et Lettres, 1947) which provides a simple and rapid method for finding the heliocentric co-ordinates of Uranus, the perturbations of the other planets having been taken into consideration in the compilation of the Tables. An explanation of the method for applying the Tables is given, and an accuracy of about 1' is obtainable, which is sufficient in a great many cases. The Tables should prove very useful, especially in investigating the influence of Uranus on the motions of comets in ancient times, though, of course, they will prove helpful in many other cases as well. Special investigations were made of the long-period inequalities of Uranus, and it seems that these, namely, those of the mean longitude, the eccentric angle, longitude of perihelion, and semi-major axis, can be approximately represented by a Fourier interpolation formula. These inequalities are so regular that the corresponding formula for perturbations in longitude can be extended even beyond the limits of the Table, for the period 6500 B.C.– A.D. 5500, with a mean error of less than 1'.
