The description and use of the globes and the orrery: To which is prefix'd, by way of introduction, a brief account of the solar system

"The Description and Use of the Globes and the Orrery" by Joseph Harris is a scientific publication written in the 18th century. This work serves as both a comprehensive guide on the structure and functions of globes, as well as a detailed exploration of the solar system and celestial mechanics. The book is likely to appeal to readers interested in astronomy, mathematics, and the history of science, providing insights into planetary motion and the tools used to understand them. The opening of the work introduces the reader to the overarching structure of the solar system, presenting the sun as the central figure around which the planets revolve in specific orbits. It outlines the order and periods of the planets, beginning with Mercury closest to the sun and concluding with Saturn, detailing their distinct orbits and characteristics. The text emphasizes the importance of mathematical observations and calculations in understanding the distances and movements of these celestial bodies, setting the stage for a deeper exploration of both the globes and orreries that visually represent these astronomical concepts.
