Your Stargate mod have this planet (Abydos) from the movie of 1994 where is locate on this planet the city Nagada ?
It does now
An'shur, if you search the forum you can find some of my own Stargate systems somewhere. Should be Abados, Lantea, and I think Orilla. If you are able to locate them, feel free to include them with your addon.
Thanks! I found Abydos, Madrona and Lantea. If you don't mind, I fixed the orbital periods of the moons of the first two planets, because it took too long for them to orbit the planets.
I included Abydos and Madrona in my addon, but not Lantea, because I found two versions of it on the old forum. pfjarschel's
version of the system contains all nine planets. I guess I will just provide a link
with both. I haven't found Orilla.
You also mentioned P3W-451 on the old forum. I also encountered a problem with making the accretion disk look as wide as in the series. It ended up accreting much faster than the speed of light. In the end I made it small and realistic, which means not so dramatic...
Regarding distance of Abydos from Earth, 89 light years is probably alright, but it is said to be among the closest planets to Earth, if not the closest (So the coordinates were still usable when first dialed, including that of Heliopolis, with similar address and therefore proximity to Abydos itself) Icarus Base is much closer than that at 21 light years away. Apophis' ship from the episode Within the Serpent's Grasp
was only a bit more than 10 light years far when SG-1 gated in. Putting Abydos and Heliopolis systems closer than 21 light years would disrupt the shapes of existing real constellations if not placed to orbit real stars. The closest together I can get them using G or K stars (including binary, not many options here really) would be 10 light years (HR 7703 and Delta Pavonis). I decided to leave Abydos at 89ly away for now.
