(THIS PROJECT IS CANON TO THE APEX LORE). Here at CCEA, we decided to measure just how speedy the planets are compared to eachother, and also the orbits of some moons (that we've fully documented). The Real Time one is here:
So far, we only have the orbits of the inner planets, because they're easier to observe, plus, we have spacecraft orbiting Keer, Blanket, and Doritas, so we've documented their orbits completely.
