UFS Nebula Classification

It has been noted that it is extreamly difficult to catagorise Nebulae and other Stellar Gas Clouds as many of them have unique properties that might be only found in that Nebula. The main Classes and divisions of Nebulaes are listed here.

Class 1 - Protomatter

Size: 85,000-90,000 km, spanning 3 Lightyears.

Composition: Proto-matter, unstable ionised compounds.

Noteable Mentions: USS Voyager NCC-74656 - 2373 - Delta Quadrant

Class 2 - Sensor Disruptive Matter

Size: 1 - 2 Light years across

Composition: Unusual matter known to distrupt starship sensors.

Noteable Mentions: USS Equinox NCC-72381 - 2375 - Delta Quadrant

Class 3 - Subspace Anchor

Size: 65,000-70,000 km

Composition: Hydrogen compounds, Subspace Vacuole is found at the center of the Nebula acting as a gravitational anchor for the surronding Hydrogen-based matter.

Noteable Mentions: Varro Generational Ship - 2375 - Delta Quadrant

Class 9 - Sensor Deciever

Size: 100,000-120,000 km

Composition: Gases inside the nebula serve as a perfect haven for damaged vessels that need to repair without disruption.

Noteable Mentions: USS Voyager NCC-74656 - 2374 - Delta Quadrant

Class 11 - Azure

Size: 15 Lightyears across.

Composition: Oxygen, Argon, Theta-Xenon, Fluorine, and Sirillium.

Notable Mentions: Azure Nebula (USS Excelsior NCC-2000 - 2293 - Beta Quadrant), (USS Aventine NCC-82602 - 2381 - Beta Quadrant)

Class 17 - Sirillium-Rich

Size: 2 Lightyears across.

Composition: Hydrogen, Helium, 7,000 per million Sirillium

Notable Mentions: USS Voyager NCC-74656 - 2372 - Delta Quadrant

Class J - Deuterium-Rich

Size: 1.4 Lightyears across.

Composition: Heavy concentrations of Ionized gases with Deuterium deposits.

Notable Mentions: USS Voyager NCC-74656 - 2376 - Delta Quadrant

Class K

Size: N/A

Composition: Helium and Argon.

Notable Mentions: USS Voyager NCC-74656 - 2376 - Delta Quadrant

Class T - "T" Shaped

Size: 1000km Diameter

Composition: Hydrogen, Helium, and Argon.

Notable Mentions: USS Voyager NCC-74656 - 2376 - Delta Quadrant, Pegasus Nebula (Argussian Federation), Omarion Nebula (Dominion).

Class Mutara

Size: 110 Lightyears Long

Composition: High levels of static discharge and was comprised largely of ionized gases.(82% dilithium hydroxyls, magnesium, and chromium (Paulson Nebula) (Possibly subnuclonic radiation).

Notable Mentions: Paulson Nebula (USS Enterprise NCC-1701-D - 2366 - Alpha Quadrant), Mutara Nebula (USS Enterprise NCC-1701 - 2285 - Alpha Quadrant), Mutara-Class Nebula (USS Voyager NCC-74656 - 2374 - Delta Quadrant)
