The Facts on File Dictionary of Astronomy - Comprehensive Science Reference Book for Students & Researchers | Perfect for Space Studies, Astrophotography & Stargazing

This book came out in 2006 and is out of date. It lacks any discussion of the dwarf planet Eris, indeed its entry on dwarf planets is unsatisfactory. The book is designed for students with a moderate to advanced appreciation of mathematics, something of which I lack. As such I have found it hard to understand. I love studying astronomy, but unless one can grasp an advanced level of mathematics, much of the information in this book tends to get pass me. Another problem is its highly selective articles on our satellites and asteroids, with only a few stars given entries. Often I would be reading another book on astronomy, find an odd word, look up the word in this book, and its definition would be too opaque to give me an answer I could understand. Therefore, the book is not for the elementary level of science students, but for those who already have a good education of science vocabulary. It often reads as a physics textbook and gets to be dense reading, with tables and charts with scientific abbreviations. It could use some illustrations and photographs that are common in more popular books on astronomy. Yet it is useful to have as one of several resources for fans of astronomy, especially when I try to read other recondite books on the solar system where the authors get caught up in the jargon used by astronomers.
