This tutorial takes everything learnt in the the first one and applies it to creating an Orbit Simulator for the Major Moons of Saturn.
Code from the first tutorial needs to be changed to make the simulator work for the Satellites of Saturn.
This tutorial shows how to generate topocentric Ephemeris for the Moon based on a desired input date and observer location.
So the position of the Moon on a certain date as seen from a specified location on the surface of the Earth.
When calculating the location of the planets in our Solar System, you don't have to take into account the geocentric parallax, as the planets are so far away.
But the Moon is an exception, which has a very large parallax (up to 1° parallactic angle).
