Astronomy improved: or, A new theory of the harmonius regularity observable in the mechanism or movements of the planetary system. In three lectures, read in the chapel of Yale-College, in New-Haven. Begun February 17, 1781. Exhibiting a new and accurate method, for investigating the velocities, distances and periods of the planets; founded on the nature of gravitation, and mathematical relations and dependencies between their distances, velocities and periods: As also for finding the quantities of matter in the primary planets; and the figure of the moon's orbit in open space / by Nehemiah Strong, M. A., professor of mathematics and natural philosophy in that college, 1784
