These have orbiting satellites. D. Neither asteroids nor comets 2. Most orbit between Mars and Jupiter. D. Neither asteroids nor comets 3-1

2 3. Short period versions of these objects come from the Kuiper belt. D. Neither asteroids nor comets 4. Long period versions of this come from the Oort cloud. D. Neither asteroids nor comets 5. These are known to pass close to Earth. D. Neither asteroids nor comets 6. These are mostly made of rock and/or metal. D. Neither asteroids nor comets 3-2

3 7. These may have been responsible for bringing water to Earth. D. Neither comets nor asteroids 8. How is the following paragraph consistent with the nature of science? This is an excerpt from the NASA NEO website. "As is often the case, the possibility of future Earth impacts for some near-earth objects cannot be entirely ruled out until the uncertainties associated with their trajectories are reduced as a result of either future position observations, or in this case, heretofore unrecognized, pre-discovery observations. When these additional observations were used to update the orbit of 2004 MN4, the uncertainties associated with this object's future positions in space were reduced to such an extent that none of the object's possible trajectories can impact the Earth (or Moon) in 2029." A. Science relies on empirical observations. B. Science is tentative. C. Science is limited by technology. D. All of the choices are correct. E. None of the choices are correct.

6 15. Does the Torino scale have a category for meteorites? A. No, they are too small to cause damage. B. No, most burn up in the atmosphere. C. Yes, they are included in level 0. D. Yes, they are included in level Suppose you were tasked to evaluate the damage risk posed by a comet that was headed toward earth. Based on what you know about the average properties of comets, how would you evaluate the risk variables of density and speed for such a comet (as compared to other NEO's)? A.
