Ranging from the sun to the most remote black holes, this compact book is a user-friendly guide to our universe. Examining our solar system in detail, Giles Sparrow moves outward through the Milky Way to other galaxies, individually discussing 300 stars, planets, moons, and such cosmological phenomena as quasars and the Oort Cloud, while stargazers will find the constellations grouped in a separate reference section. Each entry includes an image and a key information table with specifications on the mass, radius, surface temperature, distance from sun, gravity, and major elements of each object.
