Class Exercise: Using Elongation The sun, the orbits of the first 6 planets, and the largest asteroid Ceres with its orbit are shown on the next page. Although the orbits are not even remotely close to scale, you should assume that the drawing is scaled correctly for this assignment. You are now located on Ceres and all observations are now based on that location. The definition of elongation will change too (it is now the angle between the Ceres-sun line and the Ceres- planet line). The 6 planets whose orbits are drawn are the only ones you can see and are the only objects you should consider when answering the following questions. You will need a protractor to make measurements for some of the questions. Part I: Draw each of the following possible configurations on the diagram. Label the

### 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.
