Risa is located in a star called Lima Sierra, a main sequence star of class G, very similar to Sol. The planet contains one of the most sophisticated weather- and seismic-control systems in the Federation to keep under control the planet's unpredictable and violent nature.

Risa is a lush, tropical rain forest world, considered to be the top "resort planet" in the Federation. Its native people, the Risians, are well-known for their frank and open sexuality.
