You can see the distance to the planet Space Station within the hyperspace page. Click the planet you want and select the hyperspace point. If you scroll down a bit, you'll see the distance to the Space Station. You can figure out from there which is the closest jump point. Good hunting.
Honestly, i think making a jump point right near the station for every space area would be useful, i mean, really, how many people actually do anything in between the hyper exit and getting to the space station?
