The Planets

Dava Sobel has produced another beautifully written and engaging study, this time of her biggest subject yet: the Solar System. As with Longitude, Sobel is able to take what many people perceive to be a somewhat dry scientific subject and give it life. She begins with the Sun and works her way steadily outward to Pluto, which may or may not be the ninth planet, on the way painting elegant and engaging studies of each planet, summarizing what is known and what is still mysterious about each. Some may find her rhapsodies, particularly the story of Mars, told in first person by a meteorite, somewhat off-putting, but those who enjoy fine prose and solid learning will enjoy every word.

I will begin this review with a quote of Carl Sagan from his book THE COSMIC CONNECTION. "In all the history of mankind, there will be only one generation that will be first to explore the Solar System, one generation for which, in childhood, the planets are distant and indistinct discs moving through the night sky, and for which, in old age, the planets are places, diverse new worlds in the course of exploration". Dava Sobel includes this quote early in this book, and it is very appropriate for the book she wrote here. Sobel writes eloquently of our discoveries about the other planets of the Solar System, from ancient times to modern day exploration by spacecraft. She writes in a very readable style, and I can say this is a 'page turner', very entertaining and informative, even if you think you already know a lot. The price is right, too.

Why, I asked myself, would Dava Sobel pick a subject as done to death as the planets of our solar system after mining such rich veins of prose ore as the race to measure longitude accurately and Galileo from his daughter's point of view? The answer - this fantastic author can take the overdone and give it new life! In The Planets, Dava Sobel takes the reader on a tour of planetary astronomy and the 9 objects currently classified as major planets plus the Sun and the Moon with 12 very different chapters and no feeling of having read a few chapters in an astronomy textbook. Chapters 7 [SCI-FI (Mars)] and 10 [NIGHT AIR (Uranus and Neptune)] have the most interesting points of view. Chapter 7 is narrated by ALH84001, the famous Martian meteorite that contains possible signs of life, and Chapter 10 is written as a long letter from aging astronomer Caroline Herschel (sister of the discoverer of Uranus) to American astronomer Maria Mitchell. This is the kind of book I'd recommend to an avid reader who usually avoids books on science. I enjoyed this book immensely and would recommend to anyone with an interest in astronomy and history. I'm getting my copy of The Planets into my high school library as quickly as possible.

Dava Sobel's newest offering deviates from the historical path of her previous work, but the stellar prose that remains in The Planets will inevitably pull in any who wander too close. This book touches on the social, religious and intellectual aspects of the solar system from antiquity to January 2005, but cannot properly be called history; Sobel simply stuffs the most interesting stories and facts about each celestial body into a slim 231 pages (plus a glossary and a brief appendix of factual details). Of course, interesting stories and facts about the planets could easily fill a book many, many times as long. The beauty of The Planets is that Sobel (who has clearly culled from an enormous pool of potential content) selected only most fascinating and unusual to include. Few but historians of planetary astronomy and the most dedicated trivia buffs are likely to be bored by too much they already know, even though nearly everything comes from published sources. And even if the contents are old news, Sobel's packaging is a joy.

The Planets is organized into thematic chapters that, for the most part, read like separate essays. The introduction and conclusion give the context for Sobel's longtime and continuing passion for the Planets; the former is not particularly riveting, but does not detract. The chapters-there are ten including the Sun and the Moon, with Uranus and Neptune sharing one-bear titles indicating the overarching theme of each, though each theme is stretched far enough to allow a feeling of continuity as the book proceeds outward from the Sun to the edge of the solar system.

Beginning appropriately with "Genesis," Sobel's Sun chapter is perhaps the least novel (as well as the shortest). Sobel gives an overview of basic facts and trivia about the Sun, while beginning and ending with invocations of creation and drawing a few parallels between the scientific and religious stories. Mercury's "Mythology" has the easiest theme (mostly Greek, though it dabbles in other cultures), but Sobel makes it interesting by telling the scientific history of the planet through anecdotes of scientists applying the same mythological themes to their work. The integration of science and culture is even smoother in Venus' chapter, simply themed "Beauty;" highlights include poetry on Venus by scientists and literary figures alike (and what sophisticated history of science is complete without a William Blake reference?). Our own pale blue dot offers a change of pace; Sobel tromps through a brief history of the developments of Earth's "Geography," dispelling a number of common historical myths in the process. "Lunacy" vaguely revolves around Moon superstitions but is mostly filled with interesting facts.

One of The Planets' best chapters is "Sci-Fi," which is told entirely from the perspective of a 4.5 billion year old Martian rock that crashed into Antarctica sixteen million years ago. The rock tells its own story and that of Mars, explaining how its home planet has been the object of such fascination among Earth natives through science fiction. Jupiter has the honor-or shame, depending on one's perspective-of bearing the theme of "Astrology." Given it's role in the careers of Galileo, Kepler and so many other early astronomers, historians of science should appreciate Sobel's choice for the king of the planets, despite whatever offense contemporary astronomers may take. Saturn's "Music of the Spheres" addresses the numerological aspects of the history of planetary astronomy, opening with a discussion of Gustav Holst and interspersed with other musical references. Uranus and Neptune share "Night Air," which tells their stories of discoveries mostly through the eloquent correspondence of 19th-century American astronomer Maria Mitchell. "UFO" is nominally Pluto's chapter, but as the name suggest, Pluto is odd planet (if it can even be considered one) out, more similar to other recently discovered Kuiper Belt objects than its traditional brethren. Discussion of such discoveries segues into the conclusion, which brings planetary astronomy up to the ongoing investigation of Saturn and its moon Titan.

General readers will take a lot from this book: a head full of scientific knowledge about the planets, details and anecdotes about how that knowledge was produced, and an appreciation for their historical cultural significance as well. But the greatest gift Sobel grants the reader is a small piece of her enthusiasm; The Planets makes you want to, if not become an astronomer, at least do more reading on the subject.

If you are well versed in the cosmos, you will find nothing new in Dava Sobel's book. It will be the icing on your cake of knowledge. And what luscious icing it is! If your knowledge of the planets consists of basic high school science, you will be amazed and enthralled with the beauty and mystery that is our solar system. This book is beautifully well written, easy to understand, lyrical, poetic,....I could go on and on. And, from one who has been known to buy books for their covers in the hopes that the inside would be as intrigueing as the outside, in this case I was not disappointed. The cover is a work of art; so follows the text. You'll look at the night sky with a new appreciation and sense of wonder after reading this gem.
