  1. 1. whats a doughnut-shaped ring of icy objects around the Sun, extending just beyond the orbit of Neptune
  2. 7. planets that have a compact, rocky surface like Earth's terra firma
  3. 9. what occurs in the night sky when the Earth passes through the path of debris left behind by a comet
  4. 10. what is a large objects made of dust and ice that orbit the Sun.
  5. 14. what is an APPARENT change in the movement of the planet through the sky
  6. 16. rocks that have been injected as meter-sized objects into the Earth's orbit following collisions on their parent bodies.
  7. 18. a measure of how much the deviation of the curve has occurred from the circularity of the given shape.
Down
  1. 2. what is a fundamental system in condensed matter sciences and the main constituent of gas giant planets

  9. 13. what type of planet is pluto
  10. 15. a solid object arising during the accumulation of orbiting bodies whose internal strength is dominated by self-gravity and whose orbital dynamics is not significantly affected by gas drag.
  11. 17. is 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.
