Planetoid Belts

Planetary ejecta that form belts orbiting stars.

• Most planetoid or asteroid belts are composed of ice and rock.

Description

The second digit of the "PBG" element of the UWP shows how many planetoid (or asteroid) belts are in the system.

History & Background (Dossier)

Please note that Marc Miller has indicated that, in his opinion, when the mainworld of a system is size 0 (an asteroid/planetoid belt) the number of planetoid belts shown in the PBG for the system does not include the main world.
