The planet was the seventh in the Beta Epsilon-Venturi binary star system which was located near the border of the Alpha and Beta Quadrants. Thus, it was situated in a region of space between the planet Ferenginar and bordered the Romulan Star Empire. The Breen homeworld itself was highly frigid and cold due to the remoteness from its twin stars with temperatures never going above -70 degrees C. Furthermore, liquid hydrocarbons typically fell from the sky as rainfall. This highly hostile environment meant that no lifeform that lived on a Class M planet was capable of surviving on Breen without some form of advanced life support equipment. This world also lacked a hydrosphere though it did possess liquid methane oceans that covered half of the planetary surface. The only landmasses were two large rocky continents which dominated the Breen surface.
Its known that the Breen homeworld had an extensive web of shipyards in orbit around their world. (Decipher RPGmodule: Worlds)
