The same diagram is on Bruce's blog post, but in vertical form. Both were a lot of fun to make. I started off trying to use scaled measurements from a chart I've been keeping with all the precise measurements of the planets, before realising that I could simply resize the existing diagram to get all the orbits at their proper scale.
|Soltan Ephemeris Overview and Orbital Map|
as featured on Bruce's blog.
To get around this issue, I have split the image into three different scales. Each scale is consistent only within its own domain.
- Orbital distances: all planetary orbits are to scale with each other, measured from Soltan's corona. The orbits shown are at the 3 o'clock position on the orbit diagram.
- Planet sizes: all planets, including moons, are to scale with each other, and indeed with Soltan. But Soltan is so massive that only a tiny portion is visible in this diagram.
- Lunar orbital distances: all lunar orbits are to scale with each other, measured from the centre of their parent planet. They are not in scale with planetary orbital distances; putting them in scale would make them overlap with the orbs of the planets.
There is one further issue: Ghüle is so distant when it's in the 3 o'clock position that it would require the diagram's width to be more than doubled in order just to fit it in. Moreover, its orbit takes it much closer to the sun at other points, so there is no single logical distance to display it at.

These diagrams are actually mock-ups, waiting to be populated with marble-like globes, such as the Calidar rendered globe we used in the Kickstarter campaign. You'll have to wait a while longer to see those, but I hope I can make it worth the wait. The final version will likely be featured in the final book, too.
One final note: as you may have already noticed, I have added a permanent page devoted to the Soltan Ephemeris Calculator, accessible through the buttons under the site heading above. This allows easy calculation of the exact positions of the worlds of the Soltan Ephemeris by inputting a date on the Calidaran calendar.
