Polyphemus is a high-population world with a billion or more sophonts in population size.

• This world is a "Twilight Zone World", a planet that is tidally-locked to its star. It has a hot side that permanently faces the star, a cold side that permanently faces away, and a narrow twilight zone in-between.
• It is a member of the Solomani Confederation in the Capella Subsector of Solomani Rim Sector.

• This world has a colony at Teucer (world).

Description (Planetology)

Polyphemus is a freak among worlds. Long ago, it became tide-locked to its red-dwarf primary, its volatile compounds freezing out on the night side. Quite recently, however (in the last million years or so) some cataclysmic event restarted the planet's rotation with respect to its primary. How this happened is not yet known, although it's clear that there was a massive release of energy. Most of the planet's surface rocks show signs of melting, and the planet's core is much warmer than would be expected for such a small world.
