Rosseau V

From Memory Alpha, the free Star Trek reference

Rosseau V is a planet with an asteroid belt located around or near it. The region is unique in that it is surrounded by neutrino clouds that form a harmonic resonance. Eventually the resonance becomes synchronous, making the place sound like it "has a voice."

In 2365, Wesley Crusher took Salia to the holodeck and showed her, among other things, an environmental simulation of the asteroid belt of Rousseau V. (TNG: "The Dauphin")

The script spelling for this planet "Rosseau V", however several other sources, including the Star Trek Encyclopedia, as well as the episode's closed captioning, spell it as "Rousseau V."
