The Moon may thus be described as following an elliptical orbit around the Sun at a distance of some 150 million km, superimposed upon which there are small monthly oscillations. Because the gravitational force is never directed away from the Sun, the orbit, despite these oscillations, is always concave towards the Sun.doi:10.1007/978-3-642-03436-7_8Ol...

In a recent paper of the authors, two special stable orbits called as dynamical substitutes (DSs) around each triangular libration point (TLPs) are given in the real earth–moon system which is perturbed by the Sun. Due to their stability, orbits around the DSs are ideal for locating the ...
Certain aspects of the orbit of the sun about the center of gravity of the solar system and the orbit of the moon about the earth were found to stratify the years since 1901 into active, moderate and inactive years for notable episodes in the Southern Oscillation (NESO). An active year ...
