From Halopedia, the Halo wiki
Oasis VI was supposedly a human colony during the Human-Covenant War. During Operation: BLOWBACK in 2552, the ONI-commissioned prospect explorer ship Long Time Coming was registered to the colony as a cover. It is unknown if the colony really exists, or if it was simply fabricated as a cover for the Long Time Coming.
