Solar System simulation: my latest web app.
February 7, 2020 at 2:01 am
This is my latest web app, it provides a bird eye's view of our Solar System with plotting of: Mercury-Venus-Earth-Mars along with the orbit of each around the Sun:

Note: this simulation doesn't work on mobile browsers; it works only on laptops and PCs.

It may be a problem on my end, but is this supposed to do something?  All I'm getting is a list of planets and their orbit colours.

The page must fully loads.
The orbits show in a black box under the planet list.

How detailed is your modeling of the orbital mechanics.

Very detailed and accurate.
The source code for this uses data provided by NASA and scientific laws implemented via a programming language, the scientific part is opensource and was only modeling Venus + Earth; I added Mercury+ Mars + orbit colors, and did the technical part to make it work on a web browser -the original is only for pc-.

It wasn’t meant to be encouraging. All you’ve got is differently coloured rings. The orbits are circular, the perspective is all wrong. It doesn’t have any real educational value.  If you hadn’t told us what it was supposed to be, we wouldn’t know.

Kinda pretty, though.

http://www.scholarpedia.org/article/N-body_simulationsThis survey, by Dr. Michele Trenti and Dr. Piet Hut, describes how the serious scientific N-body simulators work, using trees to approximate the attraction at great distances. Such programs are able to run in O(N log(N)) time.

http://ssd.jpl.nasa.gov/horizons.cgiNASA’s Jet Propulsion Laboratory provides a system called HORIZONS that returns accurate positions and velocities for objects within the solar system. In the example code, the values used are only rough approximations; the orbital distances and planet velocities are set to the mean distances and their relative positions don’t correspond to any actual point in time – but they produce reasonable output.
