Precession refers to a gradual change in the direction of Earth's axis of rotation.
The Earth doesn't wobble around its rotation axis. The rotation axis itself rotates,so that the Earth's poles trace around a 23.5-degree circle in the sky, every 26,000years. The term that describes it is "precession".The Earth doesn't wobble around its rotation axis.

Precession of the equinox.
"Precession", a cycle that runs roughly 26,000 years.Unless you're doing some pinpoint celestial navigation, or lab-grade measurements in astronomy,you don't notice the effects of precession during the interval of your lifetime.
Procession of the Equinox
the presence of day and night proved its rotation
Earth's precession
The earths rotation effects whether it is night or day (so you'll see the moon at night).
precession
Precession is a change in the orientation of the rotational axis of a rotating body. It can be used to describe the rotation of everything from a simple gyroscope to the rotation of a planet. 420

Precession.
Precession of the equinox.
The motion of the Earth is like the motion of a top; a precession. The Earth spins on it's axis and makes a full rotation every 23 hr. and 56 min. causing day and night.
