What is it about?

In this work, the Sun–Earth–Moon system has been studied by taking the model of the Moon perturbed Sun–Earth CRTBP (BCM). The equilibrium points and zero velocity curves are the important aspects to study the Sun–Earth–Moon system. In the proposed model, the Lagrangian points do not exist, however, a dynamical substitute of the equilibrium point exist, and this dynamical substitutes are termed as an equivalent equilibria, which give periodic path as the Moon is moving around the Earth.

Why is it important?

It is noticed that due to the generated perturbation by the Moon motion, the results are affected significantly, and the Jacobian constant is fluctuated periodically as the Moon is moving around the Earth.


I hope that the researchers find this article thought-provoking.
