History and specifics[edit | edit source]
In the 2260s, Rhinegelt was considered to be a frontier planet. Most of the world had yet to be surveyed, with settlements centered within a few hundred kilometers. Port towns were similar to those of the Old West. Terrain included forests and savannahs.
In 2268, the Federation starship USS Enterprise orbited Rhinegelt for shore leave. Spock underwent his Vulcan mok farr ritual in one of the planet's savannahs, accompanied by Leonard McCoy. (TOS - The New Voyages short story: "The Hunting")
