One issue for the OP is that real star data will be missing fainter objects at greater distances, so if things like jump distances between stars matter, then you will need to start adding in randomly generated brown dwarfs and eventually red dwarfs.Starfinder Discord Official Starfinder Site Rules If it's Star Wars / Star Trek speed of plot, your 50-100 systems could be the inhabited planets across the Galaxy (and a 2D map of the Galaxy would make sense because the height dimension of the Galaxy is not that significant relative to its radius, unless you go out into the halo clusters.). If it takes a week to jump between systems then the campaign is probably restricted to a relatively small area. If we think 50-100 systems, then the choice becomes how much ground will the PCs cover in the campaign. That something else might be wonderful in all sorts of ways but it won't primarily be a campaign setting. Any more than that and you aren't designing an RP campaign setting any more you're building something else. I think Classic Traveller had it about right - 1 or 2 subsectors' worth = about 80 systems max is plenty for a campaign. Modern astronomy is pointing towards a c.50% rate for star system formation per star. I am with you that for any kind of large volume, trying to map star by star is impossible and pointless because there will be hundreds of thousands or millions of systems. 2300AD already did it in a tractable way, even without computer support at the table, by boiling the 3D map down into a tube map type representation. And if you're talking about a sphere within 50ly of Earth, it's definitely manageable. For RPG purposes, astrosynthesis will work on a laptop. You yourself linked to Elite, which works (so perhaps you were tongue in cheek). (I'd just do it in the browser console, which is a very convenient coding environment.)Ī lot of people say that, and I think it's way past its sell-by date, because computers. But I'll leave that as an exercise for the reader. This would, of course, be easier to run as an algorithm. Bang, distance.ĭistance = sqrt( (X1-X2)^2 + (Y1-Y2)^2 + (Z1-Z2)^2 )ĭistance to Sol is already known, of course. Then add those terms together and take the square root. Order doesn't matter, because you square each resulting XYZ term. The Pythagorean theorem works on any number of dimensions, which is very convenient.įirst, subtract each XYZ coordinate of one star from the other. Once you've got coordinates, it's a cinch to measure distances. Fact-check your projection to make sure you don't need to mirror-image it. Just multiply XYZ by the distance from Sol to the target star, and there you have it: grid coordinates.īe careful Cartesian coordinate spaces might have X pointing in different directions. Through the magic of vectors, dec multiplies both of those by cos(dec), and adds Z = sin(dec). RA describes a unit vector of length X = cos(RA), Y = sin(RA). And if you're serious about this, divide by 180/PI to get good old radians, but that's optional. To turn right ascension into degrees, just multiply by 15. Well, to turn minutes and seconds into decimal values to speed calculation, divide minutes by 60 and divide seconds by 3600, then add them all to the hours or degrees. And both have subdivisions called "minutes" and "seconds", which are sixtieths of the next largest unit, but are completely different sizes between the two. You can turn that into Cartesian coordinates with a little work, and then just use Pythagoras to measure distances between any two points.Ĭonveniently measured in right ascension (in the unit of hours) and declination (in the unit of degrees). The good thing here is it gives you exact equatorial coordinates for the stars. If you want to do everything by yourself, you can grab raw data from Wikipedia (which also has some nice visualisations).
