The first planet the Bosph system, in the corewards regions of the Bosph sector, Bosph I is the largest solid planet of the system.
Bosph I surface is generally cold with random pockets of volcanic activity having been recorded by the Codruan exploration teams over the centuries. Upon closer examination, the scientists of the Old Republic have hypothesized that it is this particular volcanic activity, as well as the planet's ecliptic orbit, including the gravitational pulls from the system primary Bosph and Bosph II, are the reason for the cold temperature upon this planet's surface.
The gravitational pull from the primary and Bopsh II are constantly wreaking havoc on Bopsh I. Every six standard years new fractures are created on the planet, reshaping its terrestrial face as new volcanoes erupt and burying old ones under the mountains of rock, shifting huge amount of dust and smoke into the air and creating – for a moment – a thin layer of atmosphere that serves as the shield against the star's heat.
While the planet is fairly unstable, the tectonic shifts of Bosph I also spring forth a wealth in precious minerals and materials, making mining on its surface an acceptable risk – even to the point of creating small colonies to better process the materials.
It should be noted, however, that until recent years, Bosph I was nothing more then another planetoid, located in the fringes of the Rim – and as such, it was of little interest to both the galactic civilizations aside from the native Bosph species.
