We develop a direct geometric method to determine the orbital parameters and mass of a planet, and we then apply the method to Neptune using high-precision data for the other planets in the solar system. The method is direct in the sense that it does not involve curve fitting. This paper, thereby, offers a new pedagogical approach to orbital mechanics that could be valuable in a physics classroom.

Discovering a celestial object using a non-parametric algorithm

We describe a method that does not use any orbital parameters, to arrive at the position and mass of a new celestial object, using high-precision orbital state vector data of the rest of the objects

An approximate superposition method to obtain a planet’s orbit

We demonstrate that the deviation produced by one celestial object on the Keplerian orbit of another around the Sun is largely independent of the presence of the remaining ones. Hence, to calculate

Perturbation of Uranus by Neptune: A modern perspective

The perturbation of Uranus by Neptune is analyzed in a simple model, in which the unperturbed orbits are regarded as circular and coplanar. Both the forward problem of calculating the deviation in

Game of Orbits: A Gaming Approach to Neptune's Discovery

One reason that the planet Neptune will be remembered for, is to do with the fact that it was the first planet whose existence was postulated before being observed. This was based on analysing
