Tyrus VIIa
Location:	Tyran system
Affiliation:	United Federation of Planets

Tyrus VIIa is a planet in the Tyran system, the site of the experimental Particle Fountain Project designed as a new mining technology.

In 2364, Dr. Farallon intiated the project as its inventor and supervisor. She remained as supervisor at least as late as 2369 when the USS Enterprise-D visited Tyrus VIIa to monitor the project's progress. Starfleet wanted a feasibility study for possible use of a particle fountain on Carema III. (TNG: "The Quality of Life")
