Precession, Nutation, and Barycenter

The center of mass between two objects. This is what the planets truly orbit.

This movement changes the direction of the Earth's axis and will cause the north star to change over time.

• barycenter

• precession

• nutation

• ellipse

Due the the solar system's changing barycenter, the Sun is NOT stationary.

The Earth's axis changes direction over time (but the angle of tilt does NOT change).

• Nutation

• Precession

• Barycenter

• Revolution

When the moon revolves around the Earth, the Earth deviates a little because the moon's gravity is tugging on it.
