An inhabited planet that called for help in 2367 when an abandoned barge of radioactive waste entered orbit and began to poison its atmosphere.
Gamelan V is an inhabited world featured in the fourth-season Next Generation episode Final Mission.
In 2367, just as Picard and Wesley Crusher leave by shuttle for Pentarus V, the planet's leader, Chairman Songi, sends a distress call. An unidentified vessel has settled into orbit and radiation levels on the surface are climbing fast. Riker takes the Enterprise-D to investigate and finds an old, unmanned garbage scow loaded with radioactive waste.
The barge is too unstable to destroy or simply push away, so the crew attach thrusters and then tow it with a tractor beam through the system's asteroid belt towards the sun. The job exposes the ship to dangerous radiation, and it is completed only minutes before lethal limits are reached, delaying the search for the missing captain.
