Details and history
The third planet in orbit of the Orion star system, Orion III supported a population with cordial ties to the Federation. This world was, according to some accounts, a center for gambling. In a vision quest experienced by Chakotay, he imagined being in a boxing match, with book-makers from Las Vegas, Mars and Orion III all agreeing on 33 to 1 odds that Kid Chaos would outpoint Chakotay and 11 to 1 odds that Chakotay would be knocked out by the fifth round.

ST reference: Star Charts establishes the Orion system mentioned in canon as being Pi-3 Orionis, a non-Federation location. STO video game: Star Trek Online extrapolates on the location shown in Star Charts with sector and sector block naming for the vicinity.
Since Star Charts has specific notation regarding Federation and non-Federation worlds, we can see that the political status of this world is not as a Federation member, but it is entrenched in Federation space, and is, apparently, open to exchange sports and betting information with Federation worlds.
