Herschel's work represents a rich overview of the physical world through a comprehensive study of terrestrial and celestial objects.In Outlines of Astronomy, Herschel provides an important review of what was known of the physical world in the mid-nineteenth century. His textbook appeals to both the general and the specialist reader as it discusses a range of phenomena, from Earths basic characteristics to planetary perturbations and sidereal astronomy.In Outlines of Astronomy, Herschel provides an important review of what was known of the physical world in the mid-nineteenth century.

Son of the famous astronomer William Herschel and nephew of Caroline, he was persuaded by his father to pursue the astronomical investigations William could no longer undertake; John's subsequent career resulted in a knighthood and a lifetime of accolades. Outlines of Astronomy (1849), an updated and expanded version of his 1833 Treatise on Astronomy, went through eleven editions in two decades and was translated into several languages. Outlines examines terrestrial and celestial phenomena, providing the reader with a wide range of knowledge about the physical world as a whole. The work is an important textbook, the object of which 'is not to convince or refute opponents, nor to inquire & for principles of which we are all the time in full possession but simply to teach what is known'.Preface; Introduction; Part I: 1.
