    • Outer Edge: ~0.2 AU

Celestial Bodies – UE-CM-700 System

UE-CM-700-d (TOI-700 d): Polaris — Main colony world

  • Orbit: 0.16 AU (Year Length ≈ 37.5 Earth days)

  • Spin State: 3:2 resonance modeled, avoiding full tidal lock

  • Atmosphere: Oxygen- and sulfur-rich; filtration required for exertion

  • Surface: Four major continents and one polar ice cap

  • Note: Only known habitable-zone terrestrial confirmed

UE-CM-700-b (TOI-700 b): Cauteris — Inner rocky planet

  • Orbit: 0.08 AU (Year Length ≈ 10 Earth days)

  • Surface: Tidally locked; volcanic, extreme temperatures

  • Atmosphere: Thin, likely stripped; non-habitable

UE-CM-700-c (TOI-700 c): Myrrin — Sub-Neptune

  • Orbit: 0.11 AU (Year Length ≈ 16 Earth days)

  • Surface: None; gas envelope

  • Notes: Useful as a gravitational anchor; possible high-atmosphere skimming for volatiles

UE-CM-700-e (TOI-700 e): Kholos — Dwarf rocky world

  • Orbit: 0.19 AU (Year Length ≈ 28 Earth days)

  • Spin State: Possibly ex-moon of Polaris

  • Surface: Crater-pocked basalt plains, signs of ancient lava flows

Survey Notes

  • Stellar activity is minimal. Long-term photometric monitoring shows no large white-light flares.

  • Low UV flux reduces atmospheric stripping risk; colonist respirators must still account for particulate-heavy local air rather than stellar radiation hazards.

  • Colonists have reported the sun as “Ember” in informal speech, owing to its dim red-orange glow at local noon.
