Our solar system consists of eight planets, as well as numerous moons, comets, asteroids, and meteoroids. For thousands of years, humans believed that Earth was at the center of the Universe, but all of that changed in the 17th century. Astronomers like Nicolaus Copernicus, Galileo Galilei, Johannes Kepler, and Isaac Newton proposed the unthinkable theory that Earth and the other planets actually revolved around the Sun. This engaging book chronicles the beginning of the modern age of astronomy, then follows later discoveries, including NASA’s current missions in space.
我們的太陽系由八顆行星組成，還有許多衛星，彗星，小行星和流星體。數千年來，人類認為地球是宇宙的中心，但一切都在十七世紀徹底改變了。
尼古拉．哥白尼、伽利略．伽利萊、約翰尼斯．克卜勒、艾薩克．牛頓等天文學家提出了一個不可思議的理論，也就是地球和其他行星實際上繞著太陽轉。
這本引人入勝的書記錄了現代天文學的開端，以及後來的發現，包括美國太空總署目前進行的太空任務。
