Astronomy Ranking Task: Kepler's Laws - Orbital Motion Exercise #1 Description: The figure below shows several positions of a comet traveling in an elliptical orbit around the Sun. Four different segments of its orbit (A-D), and the corresponding triangular shaped area swept out by the comet, have been shaded in gray. Assume that each of the shaded triangular segments have the same area. SUN A

Using Appendix G, complete the following table that describes the characteristics of the Galilean moons of Jupiter, starting from Jupiter and moving outward in distance. Table A This system has often been described as a mini solar system. Why might this be so? If Jupiter were to represent the Sun and the Galilean moons represented planets, which moons could be considered more terrestrial in nature and which ones more like gas/ice giants? Why? (Hint: Use the values in your table to help explain your categorization.)
Which of the following is least reasonable regarding comets? Group of answer choices Short-period comets originate in the Kuiper belt and take less than than about 200 years to orbit the Sun. Long-period comets originate in the Oort cloud and can take millions of years to orbit around the Sun, in randomly oriented orbital planes. The ion tail of a comet tends to produce a blue glow, as the ions inside it absorb sunlight and re-emit the absorbed energy with a characteristic color (somewhat like the gas atoms in a neon light or in an Aurora). An ion tail is typically narrow and straight and always trails the comet, like long hair in the wind. The dust tail of a comet often looks curved and its whitish color is just reflected sunlight.

For the following, determine whether the type of explanation offered is theoretical (the kind used in inference to the best explanation) or nontheoretical (e.g., teleological, interpretive, procedural). No one noticed the comet before because of cloud cover.
