Message: <blockquote data-quote="Umbran" data-source="post: 3197605" data-attributes="member: 177">Ah,  I gotcha.  I usually only see things within the bounds of the Kuiper Belt (out to 50 AU) to be called "in the system". My apologies - I was just using your own words: "I still have some campaign ideas that would require the PCs to travel some 60,000 AUs"Well, please allow me to rephrase.  Can you tell us why that plot element is out at 60,000 AU?  Why specifically that distance, roughly one lightyear from the star?  Is the number really important, or can you define it as "far, as the PCs measure travel"?I tend to follow a simple design philosophy - which is to not overspecify.  Otherwise, you get things like this, where you are designed into a corner, and need to come up with ways to work around your earlier definitions.  You are not working in the Sol system.  You are not fixed to the numbers we have here.  You are able to put planets and objects wherever you like, within some broad limits for verisimilitude.  Rather than define your positions, and then try to figure out how to make travel times work out, why not figure out your travel times, and then place the objects where you want them to be?Following Sol as a very rough model:  We could say that you've got a couple or few really useful planets within 2 or 3 AU of the star.  The longest distance between these will be 6 AU or less.  Decide how long you want them to take to travel between these objects.  You'll then have other objects scattered from 3 AU out to perhaps 30 AU (Neptune's orbit-ish) or 50 AU (the outer edge of the Kuiper Belt).  a) If inner-system travel is in terms of days, travel out to the outer system will probably be on the order of weeks, or tens of days. (You seem to think this is a bit fast)b) If it takes a week to get across the inner system, it'll take two or three months to reach the outer system.  (From the sound of it, you probably want this option)Now, decide how long you want them to take to get to this distant plot element.  That'll give you a distance.  If they can travel one AU a day (they take a week to get across the inner system, and a couple months to go one-way from the inner system to the outer system), and you want one way travel alone to be a year, the object is out around 300 to 400 AU.  For the Sol system, that'd be out far beyond the Kuiper Belt, beyond anything folks would call "in the system" from a practical day-to-day point of view.</blockquote>
