How far does the moon move relative to the sun during a solar eclipse
Total and annular solar eclipses occur where the Sun-Earth-Moon angle is 0$^\circ$.
Where that angle is smaller than 0.5$^\circ$ but not 0$^\circ$, there is a partial solar eclipse.
The Sun-Moon-Earth angle at those times is 180$^\circ$.
Due to the Moon's orbital inclination, most new moons miss eclipse alignment, some by as much as 5$^\circ$.
