In the movie Oblivion (Universal Pictures, 2013), Earth's moon is broken into a large irregular-shaped fragment surrounded by much smaller debris, presumably all of which orbit Earth. Classify the large irregular-shaped fragment, using the International Astronomical Union classification scheme.
Solution and grading rubric:
- p:
Correct. Of the three IAU requirements (orbits the sun, has a rounded shape, cleared/dominates its orbit) this large fragment fails all three, but failing the first requirement classifies it as a satellite/moon of Earth. - r:
Nearly correct (explanation weak, unclear or only nearly complete); includes extraneous/tangential information; or has minor errors. Understands which IAU requirements this large fragment satisfies or does not satisfy, but misclassifies typically as solar system debris. - t:
Contains right ideas, but discussion is unclear/incomplete or contains major errors. Problematic discussion of IAU requirements. - v:
Limited relevant discussion of supporting evidence of at least some merit, but in an inconsistent or unclear manner. Discussion only tangentially related to the IAU requirements. - x:
Implementation/application of ideas, but credit given for effort rather than merit. Discussion unrelated to the IAU requirements. - y:
Irrelevant discussion/effectively blank. - z:
Blank.
