Publisher's Synopsis
Super Explorers take you deep into space to see the planets in our Solar System and beyond: · Our Solar System has 8 planets, 5 dwarf planets and many minor planets. · Most planets have at least one moon like Earth, but Jupiter has 69 moons and Saturn has 62! · The Sun's gravity keeps the planets in our Solar System circling around it. · Mercury is the closest planet to the sun; the temperature there is 117ËC (243ËF). · Neptune is the farthest planet from the sun; the temperature there is -216ËC (-357ËF). · Scientists think there may be extraterrestrial life on Enceladus, a moon of Saturn, because there may be liquid water under the surface!
