Krelln, the First moon (The Dune Encyclopedia)
Krelln was the largest of the two Arrakian satellites. Krelln had the same face toward Arrakis at nearly all times.
The moon was of limited commercial use except of titanite mining operations. It also functioned as an observational facility for deep space surveillance.
Geology[]
Krelln was composed of titanium-rich silicates in the crust and mantel. The silicate mantel extended to a depth of 170 km. There was no apparent differentiation in composition which implies scant reheating following its formation. Seismic studies established small, rocky core.
Krelln had no atmosphere, and the landscape is stark. The only erosion occured due to thermal stress and particle impacts. A layer of meteoritic dust covered the surface of Krelln to a depth of 11 cm. Large numbers of craters dotted the surface of the moon, whose diameters ranged from 40 km to small pit-like features less than 1 mm in diameter.
