How many precession periods are in one nodding

Reference no: EM131002907

How many precession periods are in one "nodding" period of Earth's inclination axis and in one period of the changing shape of Earth's orbit? In the time span shown in Figure 2-11b , how many periods or fractions of periods did the Earth's axis precess, nod, and Earth's orbit change shape? Of the three periods, which is likely to have the most effect on the changes shown in Figure 2-11?
