[Star Wars] Astrogation

[Phaelen Bleux]

I'm trying to collect bits a pieces to start a SW campaign at some point. I began looking at Astrogation as it might apply to SW. A few quandries:

(1.) How hard should Astrogation skill be? M/A seems a little generous for the SW universe.

(2.) What Complexity computer would be needed to handle astrogation calculations?

(3.) How large of a database to you need to keep track of 180 billion objects in constant motion with X,Y,Z coordinates and basic planetary descriptions?
