Axial parallelism of Saturn's rings, in a 17th century work by James Ferguson (Scottish astronomer) 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 ...
Earth rotates (white arrows) once a day around its rotational axis (red); this axis itself rotates slowly (white circle), completing a rotation in approximately 26,000 years [1] In astronomy , axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical body's rotational axis .
Relationship of Earth's axial tilt (ε) to the tropical and polar circles There are five major circles of latitude, listed below from north to south. The position of the Equator is fixed (90 degrees from Earth's axis of rotation) but the latitudes of the other circles depend on the tilt of this axis relative to the plane of Earth's orbit, and ...
Parallelism may refer to: Angle of parallelism , in hyperbolic geometry, the angle at one vertex of a right hyperbolic triangle that has two hyperparallel sides Axial parallelism , a type of motion characteristic of a gyroscope and astronomical bodies
Axial parallelism is a characteristic of the Earth (and most other orbiting bodies in space) in which the direction of the axis remains parallel to itself throughout its orbit. The Earth's orbit exhibits approximate axial parallelism, maintaining its direction toward Polaris (the "North Star") year-round. This is one of the primary reasons for ...

The rotational axis of Earth, for example, is the imaginary line that passes through both the North Pole and South Pole, whereas the Earth's orbital axis is the line perpendicular to the imaginary plane through which the Earth moves as it revolves around the Sun; the Earth's obliquity or axial tilt is the angle between these two lines.
