Lab 6 / Plotting the Orbit of the Moon 3Figure 1. Lunar images.Note: Measure each image vertically through its center.\Lab 6 / Plotting the Orbit of the Moon 4Figure 2. Polar coordinate graph paper. Note: It is permissible to plot points “off” of the grid if necessary.[Hint: Your first plotted point along the 270° line will be in the margin.] Be sure to check the sketch onpage 5. If your graph does not look like the sketch, then you have not correctly prepared your graph.Ignorethese answer blanks to the left.Lab 6 / Plotting the Orbit of the Moon 5Rough sketch of how your graph should appear:c is the distance between the center of the ellipse (orbit) and one of the foci, F, which typically is the Sunor a planet (like Earth) that is being orbited.The sketch shows the following elements:▪Plotted points.▪Points are connected with as smooth a curve as possible.▪The “+” represents the Earth, which is at a focus.▪The CMO or Center of Moon’s Orbit.▪The compass arcs, which are necessary to determine the CMO.▪The distance “c” between the Earth and the CMO.▪The major axis, 2a. You can only draw the major axis AFTER the CMO is determined. It takes two points—CMOand Earth—to determine a line.▪Note that the distance “a” is the length of the major axis (2a) divided by 2.c = e∙aa = semi-major axisAB = major axis
