List of human colony planets
This is a list of (some) human-settled planets. These planets are mostly common to the settings that take place before the year 5000 or so; later settings will be handled separately.
Again, a reminder that while many of them are around real stars, these planets are fictional.

First wave of settlement
The following planets were settled between the invention of warp drive in 2985 and c. 3450. For most of this period, technical limitations with star drives limited ships to journeys of about 7.5 light-years over a period of seven weeks. (For instance, the popular Mpóngó-class colony ship carried 50.23 days worth of fuel, equating to 7.5085 light-years.) This meant that to reach most planets, ships would have to take circuitous routes consisting of ~7.5 light-year "jumps."
Thus, a trip to Tau Ceti from Sol would not be an 11.8 light-year trip, but a 31.9 light-year trip, lasting at least seven months not including time spent refueling at Barnard's Star, Ross 154, Lacaille 8760, and Lacaille 9352. These restricted routes were popularly called "tramlines."
The moon Ultima (Upsilon Andromedae d 3), was so named because it was the furthest world on these routes: while only 43.8 light-years from Sol "as the crow flies," it was 130 light-years along the tramlines. A Mpóngó-class ship took nearly two and a half years to travel that far, assuming it spent minimal time in each of the 19 systems on the way.[a]
Over the course of the 35th century, faster drives became affordable for civilians, which led to the second period of expansion, AKA the "Great Outpouring."

- ^ Note that these distances hold for the year 3250 and not the year 2023. Yes, I went to the trouble of calculating the motion of all nearby stars out to that time!
The Great Outpouring
The following planets were settled between c. 3450 and c. 3850. The period was so named as it was a period of large, sustained emigration from Earth; most settlers during this period came from there, rather than any of the established colony planets.
At the end of this period, human-settled space was roughly 160 light-years in radius, with 221 settled worlds (compared to 66 light-years and 51 worlds at the beginning).
