Beta 071
Beta 071 was an asteroid located in the Devolin system. This system was located in Sector 1607, a region of space in the Beta Quadrant.
It was located close to asteroids Alpha 331 and Gamma-601, but was much smaller than the latter. (TNG: "The Pegasus")
This asteroid was only mentioned in writing.
This asteroid's quadrant of origin is inferred based on the position of its star system as seen in the star chart appearing in the Star Trek: Picard episode "The Next Generation".
