Jaros

The Jaros System was a star system within Federation space.

The system contained two Class M planets. Jaros II was a marginally Class M world with a hot, dry climate. Starfleet maintained its stockade facility on Jaros II. Those who were incarcerated at Jaros II included Valeris, Ro Laren, and Ezri Dax. (,, and )

Jaros II's nearest neighboring planet was also Class M. Unlike Jaros II the climate of that planet was much more temperate, with a wide variety of flora and fauna present


 * The novel The Poisoned Chalice mentioned this second Class M planet, however it did not specify whether this planet was Jaros I or Jaros III.
