Answers to the "Astronomy Ranking Task: Kepler's Laws": Exercise #1: Part A. All times are the same. This is straight out of Kepler's second law, it's basically exactly what the law says. Part B. BACD. Just look at the segments that the comet travels. B looks the longest, and it is the longest. D looks the shortest and it is the shortest. Keep in mind that this question is just asking about the segments that the comet travels on, not the wedges. Part C. DCAB. If it takes the same amount of time to do all 4 segments, but some segments are longer than others, then they have to be going different speeds. If it takes you 1 hour to travel 30 miles, and your friend 1 hour to travel 60 miles, what does that imply about your speeds? Exercise #2: DCAB. An asteroid (or anything in the Solar System) moves faster on its orbit when it is closer to the Sun, and slower when it is farther from the Sun. Exercise #3: CEBDA. Kepler's Third Law tells us that we can relate the average distance (a.k.a. semimajor axis)to the orbital period. And it thus also tells

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
