How does the moon orbit vary with time?

The orbit is an ellipse in a plane inclined at an angle of with respect to the Earth.

In every revolution, Earth is the closest perigee and the furthest apogee.

Additionally, these variations over a lunar month are not fixed.

The Moon moves in relation to the Sun because of the rotation of the

Earth-Moon Arm: The Moon travels in 13+ spirals around the Earth's orbit.

Its route around the Earth's orbit in a year passes over a torus that has

the orbit of the Earth as its axis.

In addition to its elliptical orbit, which results in variations in the moon's apparent position in the sky over time, the moon also has an inclined orbit, which causes variations in the moon's distance from Earth during its monthly orbit—a phenomenon called lunar libration.
