The quasi elliptical motion of the moon
Maurizio M. D'EliseoAmong the many perturbing effects exerted by the Sun on what would otherwise be the
Kepler’s ellipse of the Moon around the Earth, it is possible to set apart a particular class
of terms of periodic and secular nature related to the size of the eccentricity and to the
location of the perigee. These matters can be jointly treated by studying the behavior of a
single mathematical entity, the eccentricity vector, a complex number that in polar form has
the eccentricity as magnitude and the angle marking the position of perigee as argument.
The comparison between the theoretical behavior of this vector and the observations has
historically represented an important test of the inverse-square law of gravitation.
