Following this is a series of charts & tables I've been making for a table-top Star Trek game for a group of friends.
The game is set from mid-2377 onwards, in the post-Dominion War era, and is based out of the starbase Deep Space 4, a couple of dozen light years from the Romulan Neutral Zone.
There's no Star Trek canon for this information; the Typhon Expanse is a sector of space unexplored by Trek lore and only referenced in a single TNG episode.
The star system information provided below is more-or-less accurate according to current astronomical and astrophysics calculations and information.
Forgive the rather lame names of the star systems; I initially started work on them a long time ago, and when I resumed on it in earnest I couldn't be bothered changing the names (changing the system names would have caused me a lot of re-work).
I just hope the tables copy'n'paste okay from OneNote; otherwise I'm in for a lot of reformatting. (Edit: nope...a lot of table formatting and re-formatting required.)
UPDATE: Questions and comments welcome - help me develop the star system and indigenous life forms! Ask me a question and I'll give you an answer (as it might fit within the bounds of the game campaign I'm developing for my players).
Most stars are currently classified using the letters O, B, A, F, G, K, and M, where O stars are the hottest and the letter sequence indicates successively cooler stars up to the coolest M class. Useful mnemonics for remembering the spectral type letters are "Oh Be A Fine Girl Kiss Me" or "Oh Boy An F Grade Kills Me". According to informal tradition, O stars are called "blue", B stars are called "blue-white", A stars are called "white", F stars are called "yellow-white", G stars are called "yellow", K stars are called "orange", and M stars are called "red", even though the actual star colours perceived by an observer may deviate from these colours depending on visual conditions and individual stars observed.
In the current star classification system, the Morgan–Keenan system, the spectrum letter is enhanced by a number from 0 to 9 indicating tenths of the range between two star classes, so that A5 is five tenths between A0 and F0, and A2 is two tenths of the full range from A0 to F0. Lower numbered stars in the same class are hotter. Another dimension that is included in the Morgan–Keenan system is the luminosity class expressed by the Roman numbers I, II, III, IV and V, expressing the width of certain absorption lines in the star's spectrum. It has been shown that this feature is a general measure of the size of the star, and thus of the total luminosity output from the star. Luminosity class I stars are supergiants, class III simply giants and class V either dwarfs or more properly main-sequence stars. For example, the Sun has the spectral type G2V, which might be interpreted as "a 'yellow' two tenths towards 'orange' main-sequence star". The apparently brightest star Sirius has type A1V.
Planetary bodies are more varied than the stars they orbit. They range in size from small moons to the size of small stars; their composition ranges from rock and metal to gas. They can be found in the uninhabitable zones of a star's aura (Hot / Cold), or they might be capable of supporting humanoid life (Ecosphere). These definitions are not exhaustive, however; a planet in a star's Ecosphere could be just as hostile to humanoid life as a planet that is orbiting on the fringe of the star's corona.
