Celestia Forums

Here's a simple addon (with toggle script) which shows the approximate orbit of our solar system through the Milky Way. The orbit pass through the Cygnus constellation, as for the real global motion around the galaxy. The orbit is also showing the oscillation through the galactic plane (about 2.7 oscillations per revolution around the galactic center) :


On the picture above, the red cursor is showing the actual position of Sol and the orbit is passing through it, of course. The pink arrow is showing the sense of the motion. The addon is also showing the controversial Galactic Habitable Zone (GHZ). Obviously, this addon can't show the motion of the MW's arms while the -fixed in Celestia- Sun is following its path.

Here's the addon (edit the included script as you wish. I'm publishing the French version) :


The script gives the usual estimated velocity (~220 km/sec) and revolution period (~240 millions of years).

Comments and suggestions are welcomed.

That’s a pretty sweat add on. I will go as far to say that Chris should add this to the default set on the downloadable.

This might have been brought up before brought up before; should we, by that I mean Chris, include this as a extra level in the Celectia. We already have extra solar planets, why not the orbit of the stars as well?

Cham, can you add 1million year ticks to the orbit.

Thnx a lot. What about English version?
