Star Trek: Bajor
▶ Explore this system live in the app
The Bajoran system is a major spiritual and political hub in the Alpha Quadrant, orbiting the star B'hava'el.
It is best known for the Bajoran Wormhole—the 'Celestial Temple' of the Prophets—and the Deep Space 9 station that guards its entrance within the hazardous Denorios Belt.

The Denorios Belt
region · orbits Bajor-B'hava'el · 92,700,000 km–104,700,000 km
Charged Plasma Navigational Hazard
A naturally occurring, highly charged plasma torus emitting a purple-pink ionization glow. Its electromagnetic interference acts as a hazardous natural border.
The Bajoran Wormhole
artifact · orbits Bajor-B'hava'el · 98,000,000 km · 12,000 km diameter
Spacetime Anomaly Stable Wormhole
A stable, highly anomalous artificial spacetime conduit to the Gamma Quadrant, discovered hidden within the treacherous confines of the Denorios Belt.
Deep Space 9
station · orbits The Bajoran Wormhole · 5,000 km · 2 km diameter
Space Station Cardassian Architecture
Originally a Cardassian ore-processing facility named Terok Nor, this massive space station was manually relocated millions of miles to guard the mouth of the wormhole.
