Even as telescopes now enable us to glimpse far corners of the universe, astronomy has throughout history been particularly a quest to the map our own solar system. Beginning with an ancient Babylonian's charting of the movement of Venus and Galileo's discovery of Saturn's moons, Anne Rooney takes a journey through the history of planetary exploration, including the modern use of rovers, flybys, and spectroscopy. Illustrated with maps, drawings, paintings, and high-resolution photographs, Rooney's text also explains the technology behind how exoplanets are now routinely being discovered.
