"The Hunt for Planet X: New Worlds and the Fate of Pluto goes beyond a standard scientific read, encompassing who, and what, is involved in the pursuit of planetary endeavors. Touching on over three-hundred years of debates, debacles and discoveries, this book offers the reader insight into the minds and motives of planetary astronomers and their findings. The "hunt" continues to the outer-most regions of the solar system, and Govert Schilling states this search will not cease: "Astronomy is an adventurous science," he writes, and without adventure and those who seek it out the universe would otherwise remain mysterious. The real-life characters presented in The Hunt for Planet X look for glimpses of light in the dark, from Icy Kuiper Belt objects to full-fledged planets, in the process challenging how such worlds should be defined and ultimately describing the Universe."--BOOK JACKET.
