The Prometheus - Alpha Centauri System

Tom Kalbfus

Here are maps A through G of the Prometheus Star System otherwise known as the Alpha Centauri System, it is the system that is closest to Terra, and it consists of three stars and their attending planets. The stars' names are Helio (Formerly Alpha Centauri A G2 V), Pyros (Fomerly Alpha Centauri B K2 V), and Proxima (Also known as Alpha Centauri C M5 V). Here is the overview map:

On this scale, 1 hex = 2000 AU, the Prometheus System splits into two components, One is the Proxima subsystem on the lower right, which hosts the sub-main world of Chiron (the name of a mythical in Greek legend as it turns out. The Chiron subsystem has four gas giants orbiting closely to this red dwarf, they are named after the four winds of Greek legend.

We zoom in a little close to the A-B Subsystem where the Mainword Promethus orbits.

On this map the scale is 2 AU per hex, and here we can see that the system splits into its two compoments A and B or Helios and Pyros, the way we can tell the difference is that Helios is the paler of the two suns, it is colored much like Terra's own Sun, Pyros, as we can see is more the color of fire, it has a golden hue. The Mainworld of this system orbits Helios, Aurora and Pegasus are the two Submain Worlds orbiting Pyros, the reason Aurora is suboptimal is primarly due to its long day, about 26 Terran days long, most humans find that objectionable, otherwise Aurora has a more Earthlike atmosphere that Prometheus and is a nice place to live. Pegasus can be termed as a cold garden world, it has large ice caps, the only tolerable climate area is right around the equatoral area, and of Course Pyros hosts the nearest gas giant to the Mainworld Prometheus, which is named Juno, after the wife of Jupiter (Not to be confused with the Terran asteroid of the same name)

We zoom in a little close in this third map of the Helios Subsystem:

Here we have the most traveled portion of the Prometheus System, as it contains the mainworld Prometheus itself inside of its orbit are the planets Icarus and Daedalus, orbiting outside of Prometheus' orbit is the outer world of Theodyssus, and the Odysseus asteroid belt

Here we move on to the next subsystem of Aurora:

The Aurora Subsystem requires to map scales to fully map all of its planets, the map above is of the inner system, Aurora is accompanied by the aptly named Lucifer and Vulcanus. Pyros is a dimmer sun that Helios, so its habitable zone is correspondinly closer.
And now we move on to the outer portion of the Aurora subsystem:

Here are the outer Auroran planets, as you can see their are just two, there is Aurora and the colder planet Pegasus, and both are surrounded by the Hercules Asteroid Belt.

Now we move on to little Proxima and its planets, the most important of which is Chiron:

The Chiron subsystem requires two maps to cover all the important parts. We have Chiron itself, a tidally locked planet which is the innermost planet in the subsystem and also the only terrestrial planet, and on this map we have the small gas giant Boreas, named after the North Wind of Greek legend. In the upper right corner is the large gas giant Notos, which I believe is named after the West Wind.

Finally we have a larger scale map showing all four gas giants ov the Proxima-Chiron system. Chiron's orbit is too small to be seen in this view, as each hex covers 5 million kilometers. The other planets not previously seen are the large gas giant Eurus, named after the East wind and the small gas giant Zephr named after the South wind.

Now in the following table I will list the Traveller stats of these planets, enjoy them!
