Axial parallelism

[1] The Earth's orbit, with its axis tilted at 23.5 degrees, exhibits approximate axial parallelism, maintaining its direction towards Polaris (the "North Star") year-round.

[6] Minor variation in the direction of the axis, known as axial precession, takes place over the course of 26,000 years.

For example, the axial parallelism of the Moon's orbital plane[8] is a key factor in the phenomenon of eclipses.

The Moon's orbital axis precesses a full circle during the 18 year, 10 day saros cycle.

In addition, the rings of Saturn remain in a fixed direction as that planet rotates around the Sun.

Axial parallelism can be seen in the Moon's tilted orbital plane . This results in the revolution of the lunar nodes relative to the Earth, causing an eclipse season approximately every six months, in which a solar eclipse can occur at the new moon phase and a lunar eclipse can occur at the full moon phase.
