Jupiter and Saturn

Jupiter and Saturn are the two largest planets in the solar system and the first two gas giant planets encountered when moving away from the Sun. They are both immensely complicated systems not unlike miniature solar systems on their own: Jupiter has 63 known moons and its own ring system, whereas Saturn is famous for its rings and 62 known moons. Astronomers are finding with some regularity new, distant moons orbiting each of these planets, so their number of known satellites continues to grow. Jupiter and Saturn, Revised Edition presents comprehensive and up-to-date information on these two fascinating planets in our solar system. Divided in two parts, this full-color resource discusses how these planets were discovered, basic data on the planets, new observations and current research findings, and much more.
