David Rothery is a professor of planetary geosciences at the Open University in the United Kingdom. Rothery published a short introduction to the Planets in 2010. The book has an introduction. The first chapter is on the Solar System. The second chapter is the Rocky Planets, The Rocky Planets are Mercury, Venus, Earth, and Mars. This chapter includes the Moon. The third chapter is on Giant Planets. The Giant Planets are Jupiter, Saturn, Uranus, and Neptune. Chapter 4 is entitled “Giant planets’ satellites, and rings” (Rothery 82). I read the book on the Kindle. The fifth chapter is on asteroids. Chapter 6 is on Trans-Neptunian objects (TNO). TNOs are large objects in the solar system beyond Neptune all in orbit around the Sun (Rothery 14). Plato and Charon are TNOs. Chapter 7 is on exoplanets, which are planets beyond the solar system. The last section of Chapter 7 is on whether intelligent life exists beyond the Solar System (Rothery 123-125). I thought the book was interesting since the book about the solar system was written from the point of someone with a deep knowledge of geosciences. The book covers a large amount of ground in a short number of pages. The book explains the planets in the solar system understandably way for a lay audience. The book includes images, tables, a section called “Further Reading” (Rothery 126-130), and an index. David Rothery’s introduction to Planets is a well-done introduction to the topic.
