Download or read book Planetary, Lunar, and Solar Positions written by Owen Gingerich and published by American Philosophical Society. This book was released on 1983 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: These tables cover the period from the mid-17th to the 19th cent. when astronomical ephemerides were evolving most rapidly. These tables resemble those previously pub. by the APS: Tuckerman's "Planetary, Lunar, and Solar Positions, 601 B.C. to A.D. 1" and "A.D. 2 to A.D. 1649" and Goldstine's "New and Full Moon, 1001 B.C. to A.D. 1651." The tables contain features consistent with the almanacs and ephemerides pub. in this period: planetary positions are computed for 12 hours U.T. (noon); and the Julian day number is given for new and full moons. An analytical essay examines the theoretical and computational developments in almanac-making in the period that bridges between Kepler and Laplace.
