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.

TRAPPIST-1
An ultra-cool red dwarf star about 40 light-years away that hosts seven known terrestrial planets.
planetary systemTRAPPIST-1 system
The TRAPPIST-1 system is a planetary system with 7 known planets in this catalogue.
exoplanet detection methodTransit Method
Detecting the tiny dip in a star's brightness as a planet passes in front of it.
exoplanet catalogueNASA Exoplanet Archive
The NASA Exoplanet Archive is the authoritative catalogue of confirmed exoplanets and their measured parameters.
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.
planetary classTerrestrial planet
Small, likely rocky planets up to about 1.6 Earth radii.
