Kolli is a relatively small planet. With a diameter roughly 2,500 kilometers, it is the smallest planet in the Duro System. With the Duros reaching the stars so early in the civilization history of this galaxy, Kolli has long been colonized as a mining location, supplying the Duros with valuable metals that are required in their spaceship construction. Crashed on the surface of Kolli is a large space station that used to be a part of Duros pride, a shipyard that saw the construction of some of the first hyperspace capable ships in the galaxy. The shipyard belonged to the Duro Delta Twelve, a venerable company specializing in space-faring crafts. Kolli has since became a place of the past, most of Duro Delta Twelve’s construction now takes place on the planet of Duro.
Kolli has a solid iron core, with plenty of iron content elsewhere within its planet surfaces, making mining iron ore from this planet relatively simple. Mining still takes place on this planet by the Duros, some miners have a family history on this very planet tracing back thousands of generations. The atmosphere of the planet consists of a sulfuric gas that corrodes many refined metals that it comes in contact with, making mining difficult, but the rewarding ores that Kolli exports keep the miners here. It is a general assumption amongst scientists that Kolli used to be a moon of one of the system’s gas giants, but this small but yet dense planet escaped the planet’s gravity, perhaps after being struck by another stellar body, and became a planet of its own as we see today.
After the arrival of the Imperial government, things have changed little for these Duros miners with the exception of human arrival every so often. Many geology students and other students of related disciplines from Corellia University visit this planet to observe how prospecting and mining is carried out. The students are often stunned in awe as they descend into some of the tunnels in enclosed railed vehicles, reaching hundreds of meters below the planet surface - despite that most of them already studied the existence of such tunnels. Professors leading such trips like to say that if a student has taken interest in the mining business, this trip seals their destiny.
