Orrery

Databank Text

This model of an alien solar system contains two stars, seven planets, and three moons.

—Two binary stars orbiting in physical contact. Proposed names: “Eido” and “Thea”. Observations at the sea surface suggest they are class M0V red dwarfs, smaller, colder, and longer-lived than Earth’s sun.
—A small, rapidly orbiting world close to the stars
—A planet with an elliptical orbit that swings close to the stars, then climbs far outward
—A gas giant with three large moons, one of which is this world (proposed name: Proteus)
—A tiny planet which shares the gas giant’s orbit, racing ahead of it
—A large, rocky world
—A cold ice giant with an inclined orbit
—An ice giant with a very large ring system

Nearby stars are also indicated by lights around the orrery, including a pulsar. Pulsars can be used as lighthouses to fix a star’s position in the galaxy. Consult the Noetic Advisor for further analysis.

Assessment: this orrery is probably a historical site. It was built by Axum with an advanced but pre-modern understanding of astronomy. Until a colony observatory can be constructed, it represents the best available information about the Eido-Thea system and the worlds near Proteus.
