Webecliptic plane and the strong solar torques drive the preces- sion of the lunar orbit plane along the ecliptic with an 18.6 yr period. But several influences (Lieskecause a slight tilt of the mean plane of orbital precession with respect to the ecliptic. The Earth’s oblateness contributes a small torque which attempts WebEarth's obliquity angle is measured from the imaginary line that runs perpendicular to another imaginary line; Earth's ecliptic plane or orbital plane (see illustration). At the moment, Earth's obliquity is about 23.4 degrees and decreasing. We say 'at the moment' because the obliquity changes over time, although very, very slowly.
