In the centuries following Sir Isaac Newton’s publication of the Law of Gravity, scientists equipped with increasingly advanced telescopes tried worked to explain anomalies in the orbital paths of planets. “Wobbles” in the orbit of Uranus led to the discovery of Neptune. Mercury also wobbles, and it was long thought that it was under the influence of a small undiscovered planet named Vulcan. This book traces the history of the search for Vulcan, and how Einstein’s Theory of Relativity finally “killed” the need for the little planet.
As history of astronomy and science, this short book is interesting. However it is not page-turning material, failing to really grip the reader.
