The biannual meteor shower, known as the Silent Twins, is rarely a sight worth investigating. The lack of atmosphere for the planet does not cause any of the rocks to break up and flare similar as in meteor showers on atmosphere protected planets. Notable about these showers is that the rocks actually bring water molecules into the planet. Usually these rogue source of water freezes upon entering the atmosphere, but the occasional meteor will impact into the ice packs and as a result of the collision, the water molecules will join up with the ice packs. It is rumored that the ice packs of Tarzog grow a mere one-tenth of a millimeter within a millennium.
Tarzog is considered too uncomfortable a terrain for most mining companies. And since very few pirates have ever been reported in the H'nemthe sector, there is little reason for any government to pay the planet much attention. Hence it is currently ignored.
