The 2D planets in SE4 _do_ move. The static appearance of a system is more a relation of the distance between:
- The star(s) forming the heart of the system.
- The orbiting bodies of the system (planets, asteroid fields, etc.)
- Warp points within the system.
Looking at this as a relational model, we can stipulate that the Eart revolves around Sol within a small range (at least in astronomical distances.) Placing a Warp Point on the solar plane (comparative to Earth) at a specific distance from Sol, even taking into account the rotation of the earth, at the true range, the distance, again astronomically speaking, approaches insignificance.

I had to lecture some friends on this point for several hours. My personal feeling is that it's done because to rotate 100+ systems would be processor intensive and not really worth in (at least, in astronomical terms...)
