Recall the moon's orbit
>`
- The plane of the moon's orbit is close to the plane of the earth's
orbit about the sun.
- So the moon is always close to the ecliptic.
- The moon orbits the earth in a counterclockwise direction as
seen from the north.
- The moon orbits the earth in about a month.
- So the moon moves around the elciptic in about a month.
