Rigel X, is the tenth planet of the Rigel system, in the Beta Quadrant. It is a Class J superjovian gas giant, twice the size of Jupiter. It emits radiant heat.

Kolhor

Rigel X is best known for its moon, Rigel Xb, or Kohlor, which is often called simply "Rigel X" itself. Kohlor is a large Class H moon, with a gravity of 0.8 g. It is a cold desert world, 45% covered in water ice and snow, with a thin oxygen/argon atmosphere. The radiant heat of Rigel X keeps the moon just barely livable.

Nevertheless, Kohlor is home to some 2 million people from many species, and 100,000 Orions, including both permanent residents and itinerant traders, spies, mercenaries, and starship crews from many worlds. They formed a cosmopolitan society based entirely around trade, and managed by a corporate government. Nearly all their activities took place indoors and underground, in Kohlor Station. It was known as the "Rigel colony" to Starfleet in 2161.

History
Formerly an Orion research facility, Kohlor Station was founded during the Fourth Orion Empire some 30,000 years ago. Ever since, it has served as the primary trade entrepót (a tax-free trading post and trade-route intermediary) of the Rigel system. Even the most ancient civilizations who'd forgotten their navigational data for the other worlds of Rigel still possessed complete records for Rigel Xb.

The very first Starfleet vessel to visit the Rigel system was the Enterprise (NX-01), when Captain Jonathan Archer tracked the Klingon Klaang and the Suliban Cabal to Rigel X in 2151. It returned in 2155 with Shran to track Orion slavers that had kidnapped Aenar from Andoria, and again in 2161 to find Shran's kidnapped daughter Talla . Since that time, Starfleet activity has only increased, both at Rigel X and in the rest of the Rigel system, but was never without incident.

The development of dilithium mining on Rigel XII brought increased profits to Kohlor.

It was still in business and unchanged in the late 24th century, even after the Dominion War, and remained neutral and independent.

Activities
Kohlor Station covers approximately 400 square kilometers, and is situated on a libration point at which Rigel X is visible for 50% of the time, and unseen for the rest. The surface is mainly spacecraft landing docks and repair bays, while the rest of the station facilities are underground, going down for kilometers, with a commercial habitation complex 36 levels deep. It includes many individual trade entrepóts, supply bays, workshops, homes, and various forms of night-time entertainment. It was densely packed, and even natives could get lost if they got far out of their familiar areas. It also contained cold slum areas for the homeless and impoverished transients. There was also a slave market operated by the Orion Syndicate.

As well as the possibility of trade, Kohlor Station produces hydroponically grown food, water harvested from the ice, and a variety of other supplies and services to passing ships, along with decadent entertainment for R&R. Those on the station also mine and refine Helium-3 and antimatter from Rigel X's orbit, which they sell. A defense grid dating back to the Fourth Orion Empire protects the world from most attacks bar the most extreme, while Rigel X's outermost position in the system and reduced gravity make navigation easy, thus making it an attractive place to trade. It is considered a gateway between the wider galaxy and the mysteries of Rigel.

Fauna
The world is also home to a species resembling a large fly and several colorful butterflies.
