In the 24th century, the fifth planet orbiting Mira Antlia, Dytallix B, was the location of a mining colony. It was one of seven mining colonies established by the Dytallix Mining Company for the United Federation of Planets. By 2364, the Dytallix Mining Company had abandoned the planet, leaving behind a ghost town. In that year, the starships USS Enterprise-D, USS Horatio, USS Renegade, and USS Thomas Paine rendezvoused at Dytallix B for a secret conference. (TNG: "Conspiracy" )
