Jump map from Travellermap.com

Sirius is a ring of many small worldlets (planetoids AKA an "asteroid belt"), not capable of retaining an atmosphere or water, and both non-agricultural and preindustrial in nature.

• 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.
• The worldlets are, for the most part, unable to produce quality foodstuffs and must import them.
• These worldlets are working towards being an industrial world but lack an adequate workforce to do so.
• This is a "high technology" world with technology achievements at, near, or above the standard for Charted Space.
• This world toils under the control of a military government with conditions reflecting that situation, including curtailed civil rights and limited freedoms.
• This is a "Puzzle" world designated as an Amber Zone. Caution is advised since the world has an environment, laws, customs, life forms, or other conditions that are not well understood and might be a danger to a visitor.
• It is a member of the Third Imperium in the Dingir Subsector of Solomani Rim Sector in the Domain of Sol.

Description (Astrography & Planetology)

The Sirius system "mainworld" is an asteroid belt.

• The Sirius system is a binary star system consisting of a blue-white A class star and a nearby blue-white degenerate ("white dwarf") companion orbiting about 20 AU apart. Neither has planet or asteroid companions. The belt at Sirius is actually made up of dozens of artificial satellites and habitats, including ice-rich planetoids moved from other nearby systems. These are intended to fill what was once referred to as the Sirius Gap.

Sirius has two stars in the star system.
