Yes, but sorta. Not really close the border, but more like set up a threat matrix. If there is starlane type of travel, that's one way to control who enters your systems, but otherwise, no real way that I can see. 

Well this is in response to reply 115 and 118 if there is any idea that suggests that your space is closed off unless you have open borders then I don't want any idea remotely like this. I don't really care how the Ai views me encroaching their territory. I'm not talking about you trying to forcefully throw me out of your territory. Uf this is really to hard of an option then we can forget about the whole thing. You do always have the option of not using this option. I think the Ai should be programmed that because of the fog of war the Ai can't see anyone that they can't see. If you like I got a really good argument why we shouldn't have this option. If we hadn't even decided on what it means to close borders then I will change my position on this whole site, I'm cool with not having this option. 

That's right - otherwise, a planet 30-45 parsec (2-3 squares) away from its sun would be a bit on the frosty side...

Out of curiosity, where did you come up with a 10-15 parsec per tile number? The only things that I can see in that number range are estimates of the size of tiles in the neighborhoods of planets and stars, but those numbers are in AU, not parsecs.

Also, I'm reasonably certain that a planet 30-45 parsecs away from a star could not reasonably be said to be in orbit of that star, as that's something like 97.5-146.25 lightyears away from the star in real parsecs, rather than the 'adjusted' parsecs described in the post Gaunathor linked (if using 'adjusted' parsecs, all bets are off because the relationship between real and 'adjusted' parsecs isn't clear and varies with proximity to large masses; however, it is likely still a fairly extreme range because the distance between a star and its planets in 'adjusted' parsecs is about 1 'adjusted' parsec based on the way GCII displays star systems on the map).
