Document Summary

The cycles of the moon: moon orbits eastward around the. Orbital period of the moon relative to fixed stars, is about 27. 3 days: moves relative to the background of the stars. For half the month, the moon is above the ecliptic and for the other half it is below. Nodes: the points where the moon passes through the earth"s orbital plane (points. If line of nodes does not point towards the sun, there is no chance for a lunar eclipse. Refer to different amounts of illuminated surface of the moon that we observe. The moon always keeps the same side facing. Always see same features on the moon, never see far side of the moon. The changing shape of the moon as it passes through its cycle of phases is produced by sunlight illuminating different parts of the side of the. At new moon, sunlight illuminates the far side of the moon which is not visible to us.
