Planet Earth provides factual information explaining the physical world in which we live by first setting the Earth within the context of the planetary system which orbits the Sun. Inevitably, because Earth is part of a bi-planetary system, the book explains how the Moon was formed from the Earth at a time very close to the beginning of the solar system, and how it has influenced the evolution of the Earth.
