  1. 6. A region of the solar system beyond the orbit of Neptune, believed to contain many comets, asteroids, and other small bodies made largely of ice.
  2. 7. The average distance from the Earth to the Sun, approximately 93,000,000 miles.
  3. 10. A line of cliffs formed by the faulting or fracturing of the earth's crust.
  4. 11. Occurs when one heavenly body such as a moon or planet moves into the shadow of another heavenly body.
  5. 15. Earth-like planets made up of rocks or metals with a hard surface.
  6. 17. A region of space between the orbits of Mars and Jupiter where most of the asteroids in our Solar System are found orbiting the Sun.
  7. 18. A celestial object consisting of a nucleus of ice and dust and, when near the sun, a “tail” of gas and dust particles pointing away from the sun.
Down
  1. 1. Happens when Earth passes through the path of a comet.
  2. 2. Any of innumerable small bodies of accreted gas and dust thought to have orbited the Sun during the formation of the planets.
  3. 3. A large planet mostly composed of helium and/or hydrogen.
  4. 4. A measure of the deviation of an elliptical path, especially an orbit, from a perfect circle.
  5. 5. A fundamental system in condensed matter sciences and the main constituent of gas giant planets.
  6. 8. A small body of matter from outer space that enters the earth's atmosphere, becoming incandescent as a result of friction and appearing as a streak of light.
  7. 9. A celestial body resembling a small planet but lacking certain technical criteria that are required for it to be classed as such.
  8. 12. Any of the five regions of the surface of the Earth that are loosely divided according to prevailing climate and latitude.
  9. 13. A small body moving in the solar system that would become a meteor if it entered the earth's atmosphere.
  10. 14. A meteor that survives its passage through the earth's atmosphere such that part of it strikes the ground. More than 90 percent of meteorites are of rock, while the remainder consist wholly or partly of iron and nickel.
  11. 16. The orbital motion of a spatial body in a direction that is opposite of what is normal in a given system.
