Author: FastFourierTransform Original thread on the forum: link This is a continuation of this discussion. Watsisname: I did try directly computing orbits with and without perturbation just to try to get some intuition for how the perturbation effect works. For starters I assumed co-planar, circular orbits, and also...
Historical notes about discovery of Neptune Author(s): Propulsion Disk, FastFourierTransform, Watsisname Original discussion started on the forum: here Propulsion Disk: The first theory of Neptune's existence was made by Galileo Galilei, on December 28, 1612, probably one of the most well known astronomers, was once looking at the...
Insights for a complementary explanation of Lagrange points from inertial reference frames Author: FastFourierTransform Original post on the forum: link I want to try to address this. As Watsisname said; establishing a non-inertial co-rotating frame of reference has many advantages in terms of understanding the actual situation but...
Gravitational balance and stable configurations in rotating reference frames Author: Watsisname Original post on the forum: link Introduction When two masses move in a circular orbit about each other, five points of gravitational equilibrium are generated, which move along with them. A particle placed at one of these points will have...
Author: Watsisname Original post on the forum: link Background Often in discussions of Mercury's perihelion advance, the effect is shown greatly exaggerated. Sometimes even the orbit is shown much more eccentric than it really is. Before we dive in, let's take a moment to get some perspective on...
