Initial state for a 3-body problem to create Figure 8 [ restricted to 2D ]
I've made an n-body simulation solution using the naive algorithm of O(n^2) in my library ChelseaaJS.
I was trying to make some pleasing 3 Body simulations.
I wanna do the 8 figure thing.
I know it's ...

Does one need to consider relativistic effects when simulating the (or any) Solar system?
There was a question over at Physics asking how to improve a home-brew numerical simulation of the Solar system.
Even though in that case the defects were likely numerical, I started to wonder whether ...

Which will destroy the Earth first: the Sun or Jupiter?
The sun is expected to grow in brightness over time, slowly heating the Earth until the oceans evaporate, leaving the planet uninhabitable.
Jupiter is the source of the largest perturbations to Earth'...

Peculiar Amplitude of Earth's Orbit in Z Axis
I'm currently building an N-body simulator for my masters project and I'm using JPL's Horizons system to compare against.
I started with just a couple orbits and everything seemed to be working ...

How to scale down solar system data to simulatable values
Okay, I am seriously ashamed for asking this especialy when I geniualy study on physics but there is something that bugs me with the simulation I am working on.
I am re-creating the solar system in an ...

Look up current positions and velocities of solar system objects
I am working on an orbital dynamics code and, for fun, I would like to model the Sun-Earth-Moon system with my code. I can look up the masses of each object just fine, as well as average distances ...

Where can I find a set of data of the initial conditions of our solar system?
As the title suggests, I'm in need of a set of data of our solar system. Similar to this http://bima.astro.umd.edu/nemo/archive/#iau25, but more specifically, the Dubinsky Milky Way-Andromeda data.
I'...
