System Data[edit]

Chalcyon System[edit]

The primary is an unnamed ordinary yellow main sequence star. It has a luminosity of 0.778 Sols, a mass of 0.96 Sols, and a diameter of 1.299 million km. The inner system consists of (I) an exotic atmosphere radworld, and (II) an exotic atmosphere stormworld. (III) a dense atmosphere hospitable world orbits within the habitable zone. (IV) a sparse stony planetoid belt, (V) a small gas giant, and (VI) a trace atmosphere iceworld form the outer system. Many of the worlds retain satellites.

Red Main Sequence Star Subsystem[edit]

The companion is an unnamed ordinary red main sequence star that orbits the primary at a mean distance of 75.2 AU (orbital position (XI), 11.2 billion km) and has an orbital period of 665 years. It has a luminosity of 0.0202 Sols, a mass of 0.3942 Sols, and a diameter of 604,000 km. (I) a dense stony planetoid belt, and (II) a very large gas giant form the outer system.

Mainworld Data[edit]

No world within the system has been designated the mainworld.
