Circumstellar habitable zone
In astronomy and astrobiology, the habitable zone (HZ), also known as the circumstellar habitable zone (CHZ), or as the Goldilocks zone, is the range of orbits around a star within which a planetary surface could potentially support liquid water.

Circumstellar habitable zonedepends onTemperatureEstablished
circumstellar habitable zone depends on Temperature.
Mechanism: The habitable zone is the orbital band where a planet's temperature allows liquid water.

System context
Continuously habitable zoneis aCircumstellar habitable zoneEstablished
Open Continuously habitable zone →
Habitable over the long run.
Mechanism: It is the narrower band that stays in the habitable zone as the star slowly brightens.
Habitable zone edgesis part ofCircumstellar habitable zoneEstablished
The zone's inner and outer walls.
Mechanism: The habitable zone runs from the runaway-greenhouse edge to the maximum-CO₂ greenhouse edge.
Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Removing this node severs the only sampled structural route between Continuously habitable zone and Habitable zone edges — a non-redundant bridge here.
structural · Structural removal simulation — not a historical or causal counterfactual.
75% of its relationships cross field boundaries, reaching 5 other disciplines — unusual in a discipline where most concepts stay within their field.
structural · Structural graph analysis — not a claim of importance, causation or history.
Currently dark in the atlas: no key date stored · 4 of 4 of its relations lack claim-level evidence.

Strengths & constraints
Strengths
- Cross-disciplinary connector — 75% of its relationships cross field boundaries. structural
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- Non-redundant bridge — removing it severs a sampled route between neighbouring clusters. structural
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Its dependency reading rests on 1 foundation relation. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
