Visual knowledge graph
Relationships, not isolated facts
This viewport is generated from the Asteria knowledge graph. Science, culture, and interpretive links remain separated by domain so visual context never changes the evidentiary meaning of a relation.

habitable zone candidateHabitable zone
The habitable zone is the range of orbits around a star where a planet could, in principle, hold liquid water on its surface. Lying in the zone is not a guarantee of habitability.
