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 Ceresand 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 configuration with the problem number. If it is not possible, cross out the configuration. 1.Mercury at superior conjunction
