Pentarus V was the M-class inhabited fifth planet in the Pentarus system. The planet had a mining settlement whose inhabitants mined for deposits of salenite. In 2367, when there arose a dispute among the miners, the planet requested a mediator from the Federation to settle the dispute. The mining shuttle Nenebek was carrying Captain Jean-Luc Picard and Ensign Crusher to the planet for mediation when the vessel suffered a thruster failure and crash-landed on Lambda Paz. After the shuttle disappeared, Pentarus V was searched. (TNG: "Final Mission" )
