Description
Book SynopsisThe Explanatory Supplement to the Astronomical Almanac offers explanatory material, supplemental information, and detailed descriptions of the computational models and algorithms used to produce
The Astronomical Almanac, which is an annual publication prepared jointly by the US Naval Observatory and Her Majesty's Nautical Almanac Office in the UK.
Like
The Astronomical Almanac, The Explanatory Supplement provides detailed coverage of modern positional astronomy. Chapters are devoted to the celestial and terrestrial reference frames, orbital ephemerides, precession, nutation, Earth rotation, and coordinate transformations. These topics have undergone substantial revisions since the last edition was published in 1992.
Astronomical positions are intertwined with timescales and relativity in
The Astronomical Almanac, so related chapters are provided in
The Explanatory Supplement.
The Astronomical Almanac also includes information on lunar and solar eclipses, physical ephemerides of solar system bodies, and calendars, so
The Explanatory Supplement expounds upon each of these topics as well. The book is written at a technical, but non-expert level. As such, it provides an important reference for a full range of users including astronomers, engineers, navigators, surveyors, space scientists, and educators.
Trade Review'Careful measurements have always been the key to mastery of planetary and stellar dynamics and the cosmic distance scale. The material detailed in this book is the very bedrock underlying much else that we know about our own solar system and beyond.' - Roger W. Sinnott, Senior Contributing Editor, Sky & Telescope
