Compiled by a team of experts, this textbook has been designed for introductory university courses in planetary science. It starts with a tour of the Solar System & an overview of its formation. The composition, internal structure, surface morphology & atmospheres of the terrestrial planets are then described. This leads naturally to a discussion of the giant planets & why they are compositionally different. Minor bodies are reviewed & the book concludes with a discussion of the origin of the Solar System & the evidence from meteorites. Written in an accessible style that avoids complex mathematics, & illustrated in colour throughout, this book is suitable for self-study & will appeal to amateur enthusiasts as well as undergraduate students. It contains numerous helpful learning features such as boxed summaries, student exercises with full solutions, & a glossary of terms. The book is also supported by a website hosting further teaching materials.
