All About Space. Guide To The Solar System 4ed 2025

Textbook in PDF format

Our Solar System is one of the most interesting places in the galaxy – perhaps in the entire universe. It’s the only place we know of so far that harbours life, on one small blue-green planet in the habitable zone of its star. But our planetary neighbours are interesting in their own right too. In this complete guide to our circumstellar neighbourhood, you’ll discover everything you need to know about them, from the warm rocky world of Mercury to the distant orbit of the object scientists call Farfarout. You’ll discover a wealth of worlds – not just the main eight planets but some of the moons that orbit them, and the dwarf planets that swing through the outer reaches of transneptunian space. The planets and moons of our Solar System will be some of the first places humans will explore when we finally venture beyond our own Earth and Moon. Isn’t it time you got to know them?
