WebA solar eclipse occurs when the new moon passes directly between the Earth and the Sun (Figure 24.23). This casts a shadow on the Earth and blocks our view of the Sun. A total solar eclipse occurs when the Moon’s shadow completely blocks the Sun (Figure 24.24). When only a portion of the Sun is out of view, it is called a partial solar eclipse.

The angle between those two planes is approximately 5.14° (it varies by ~±0.15°, mostly due to perturbation by the Sun). Precession causes the orientation of the lunar plane to vary, but the angle between the two planes stays (almost) the same. astronautenanzug material

Precession of eclipses

http://www.jqjacobs.net/astro/eclipse.html Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, if the axis of rotation of a body is itself rotating about a second axis, that body is said to be precessing about the second axis. A motion in which the second Euler angle changes is called nutation. In physics, there are two types of precession: torque-free …
