Joash

The moon Joash is the only natural satellite orbiting the planet Azmaveth, the first planet of the Judah system. It orbits is parent planet at a distance of about 170,000 kilometers. Joash, is a lifeless, airless rock. However, the small moon does seem to have a small amount of geologic activity churning beneath its surface. It would seem that Joash formed relatively recently when a large planetoid impacted Azmaveth sometime in the distant past. Josh coalesced out of the debris of that impact. The heat beneath Joash's surface is the remnant of that catastrophe, prolonged by the gravitational stresses of the sun Judah and the planet Azmaveth.

Joash is primarily composed of aluminim and fluorine, like it's parent planet, with an interestingly large amount of iron and magnesium, presumably from the remnants of the planetoid that caused the impact that created Joash.

Surface
Joash's surface is rocky and mostly flat, covered in craters and canyons and small mountain ranges. The ground is mainly a gray-tan color, given it's aluminum-magnesium mix.

Small topaz crystals can be found deep in the deepest canyons, where the aluminum-fluorine mixture of the rock is most evenly distributed, but mostly the surface is just bumpy plains of silicate rock.
