Chapter 3, Lessons 1 and 2 Study online at quizlet.com/_1hh10o 1. Asteroid Rock that revolves around the sun 18. Saturn 2. Comet Mixture of frozen gases, ice, dust, and rock that move in an orbit around the sun. Gas giant known for its spectacular ring system, no solid surface, 53 known moons 19. Solar System Made up of a star and the objects that surround it 20. Terrestrial Planets Another name for inner planets - refers to their rocky structure 21. Uranus Ice giant that looks like it is rotating on its side because of the angle of its axis, rotates in retrograde, faint ring system, 27 moons 22. Venus Slightly smaller than Earth, rocky cratered and volcanic, thick toxic atmosphere, spins in retrograde, no moons, no rings Dwarf Planet Spherical object that orbits the sun and does not clear its orbit of smaller debris (Pluto, Eris, Ceres) 4. Earth Rocky, solid surface with mountains, valleys, canyons, and plains 5. Galilean Moons Jupiter's largest moons. They are named Ganymede, Callisto, Io, and Europa 6. Gaseous Planets Another name for the outer planets - refers to their gaseous structure 7. Inner Planets Four planets closest to the sun. These planets are all: - made of rock - do not have rings - have 2 moons or less - are smaller than the outer planets - are hotter than the outer planets 8. Jupiter Largest planet in our Solar System, has 50 known moons, faint ring system, great red spot is a storm 9. Mars Solid rocky surface with volcanoes, impacts, crustal movements, and dust storms that alter its surface, two moons, no rings, known as the red planet due to iron minerals in soil 10. Mercury Smallest planet in our Solar System, closest planet to the sun, solid and cratered surface, no moons, no rings 11. Moon Natural object that orbits a planet 12. Neptune Ice giant that is farthest from the sun, methane gives this planet its blue appearance, 13 moons named after Greek myths, 6 rings 13. Outer Planets Four planets beyond the asteroid belt. These planets are all: - made of gases - have rings - have 10 moons or more - are larger than the outer planets - are colder than the outer planets 14. Planet Large object that orbits a star 15. Retrograde Motion Spinning from East to West as opposed to West to East. Planets that spin in retrograde appear to be spinning backwards. These planets are Venus and Uranus. 16. Revolution One complete trip around the sun. The length of the planet's year is dependent on the time it takes to complete one revolution. 17. Rotation One complete spin on an axis. The length of a planet's day is dependent on the time it takes to complete one revolution. 3.
