Quick Quiz
Choose the best answer to each of the following. Explain your reasoning with one or more complete sentences.

Students have asked these similar questions
how do you compare us with people from the moon. Explain?
The moons Prometheus and Pandora orbit Saturn at 139,350 and 141,700
kilometers, respectively.
a. Using Newton's version of Kepler's third law, find the orbital periods of the
two moons.
b. Find the percent difference in their.distances and in their orbital periods.
c. Consider the two in a race around Saturn: In one Prometheus orbit, how
far behind is Pandora (in units of time)? In how many Prometheus orbits
will Pandora have fallen behind by one of its own orbital periods? Convert
this number of periods back into units of time. This is how often the
satellites pass by each other.
Research the decision to demote Pluto to dwarf planet status. In your opinion, is this a good example of the scientific process? Does it exhibit the hallmarks of science described in Chapter 3? Compare your conclusions to opinions you find about the debate, and describe how you think astronomers should handle this or similar debates in the future.
