Castor (SR 2339) is a high-population ring of many small worldlets (planetoids AKA an "asteroid belt"), not capable of retaining an atmosphere or water, and are both non-agricultural and industrial in nature with a billion or more sophonts in population size.
- These worldlets warrant hazardous environment precautions.
- Life in a vacuum requires great discipline. After all, it only takes one forgotten seal on a vacuum suit to spell death. Those who survive tend to be very methodically-minded and attentive to small detail.
- As a group of industrial worldlets, well-developed manufacturing and processing sectors are major business here. Manufactured goods are a major export item.
- The worldlets are, for the most part, unable to produce quality foodstuffs and must import them.
- This is a "high technology" world with technology achievements at, near, or above the standard for Charted Space.
- It is a member of the Solomani Confederation in the Gemini Subsector of Solomani Rim Sector.
- This world has a colony at: Narodnya (world)
