Use the right-hand rule to find the direction of the orbital angular momentum of the Earth as it orbits the Sun as sketched in Figure 9.17.

Figure 9.17 The Earth’s spin angular momentum  lies along a direction parallel to its north– south axis. The vector   is tilted at an angle of approximately 23.5° away from the normal to the Earth’s orbital plane. The seasons indicated in the figure are those in the Northern hemisphere.
