Uranus
There is no life on Mars. And there are no "canals" on its surface. Scientists have ascertained this information from the Viking spacecraft landing in 1975. Astonishing pictures of the red planet are some of the highlights of this book that illuminate the way we think about Mars and about space. Simon has combined these vivid resources, with his characteristic spare, smooth prose in this title, a companion to The Sun, Stars, Jupiter, Saturn and (most recently) Uranus. Readers learn that Mars (named for the Roman god of war) is closer to Earth than Venus, and that the Martian year is 687 days long. Simon brings information home with analogy and anecdotes, helping young astronomers to visualize and ponder the mystery of the heavens. Ages 4-8.Copyright 1987 Reed Business Information, Inc.--This text refers to an out of print or unavailable edition of this title.
