Find and record the following properties of the ellipse in terms of Lunar Radii:
(These properties require either measurement and calculation or just calculation. You will need your calculator to convert from millimeters to Lunar Radii.)
a. The Semi-Major Axis (a): 4
b. The Semi-Minor Axis (b): 2
c. Measure the distance from the intersection of the lines for the major and minor axis to the center of the Moon at (0,0). This distance is labeled, δ.
