Visual Astronomy


Book Description

Visual Astronomy introduces the basics of observational astronomy, a fundamentally limitless opportunity to learn about the universe with your unaided eyes or with tools such as binoculars, telescopes, or cameras. The book explains the essentials of time a






















The Motion of the Moon,


Book Description

The passage of the Moon across the night sky has long been a familiar, but mysterious, sight to man. Newton, with his laws of motion and inverse square law of gravity, was able to predict all the planetary orbits, at least in principle. However, an exact solution of the Moon's motion in the gravitational fields of the Sun and Earth defeated Newton and all his successors. The Motion of the Moon is a comprehensive account of the theoretical developments right up to the present day. All astronomers, physicists and mathematicians interested in the Moon will find this a very stimulating book.




Lunar Sourcebook


Book Description

The only work to date to collect data gathered during the American and Soviet missions in an accessible and complete reference of current scientific and technical information about the Moon.




The Hill-Brown Theory of the Moon’s Motion


Book Description

This book, in three parts, describes three phases in the development of the modern theory and calculation of the Moon's motion. Part I explains the crisis in lunar theory in the 1870s that led G.W. Hill to lay a new foundation for an analytic solution, a preliminary orbit he called the "variational curve." Part II is devoted to E.W. Brown's completion of the new theory as a series of successive perturbations of Hill's variational curve. Part III describes the revolutionary developments in time-measurement and the determination of Earth-Moon and Earth-planet distances that led to the replacement of the Hill–Brown theory in 1984.
