Planet

A planet is a large, rounded astronomical body that is generally required to be in orbit around a star, stellar remnant, or brown dwarf, and is not one itself.

Dependencies

What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.

Foundations · builds on

Planetdepends onOrbitEstablished

Open Orbit →

planet depends on orbit.

Mechanism: Being a planet depends on holding an orbit: a planet is defined partly by moving in a stable path around its star and clearing that path of debris.

Sources:
Planet formationcausesPlanetEstablished

Open Planet formation →

Planets form from a young star's disc.

Mechanism: Dust and gas orbiting a new star clump together and sweep their paths clear to become planets.

System context

Exoplanetis aPlanetEstablished

Open Exoplanet →

exoplanet is a kind of planet.

Mechanism: An exoplanet is a planet that orbits a star other than the Sun — the same kind of world, just in another solar system.

Sources:
Magnetosphereis part ofPlanetEstablished

Open Magnetosphere →

A magnetic shield.

Mechanism: A planet's magnetic field carves a magnetosphere that deflects the stripping stellar wind.

Planetary atmosphereis part ofPlanetEstablished

Open Planetary atmosphere →

An atmosphere wraps a planet.

Mechanism: The planet's gravity holds a shell of gas that shapes its temperature, weather and chance of life.

Planetary differentiationis part ofPlanetEstablished

Open Planetary differentiation →

Planets settle into layers.

Mechanism: Heat lets a young planet's dense metal sink to a core, leaving mantle and crust.

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 Habitability and Magnetosphere — a non-redundant bridge here.

    structural · Structural removal simulation — not a historical or causal counterfactual.

  • 38% of its relationships cross field boundaries, reaching 4 other disciplines — a cross-disciplinary connector.

    structural · Structural graph analysis — not a claim of importance, causation or history.

  • Currently dark in the atlas: no key date stored · 8 of 8 of its relations lack claim-level evidence.

    atlas representation · Describes the current Thinking OS representation, not the state of the world.

  • Builds on 2 foundations (requires / depends-on / derived-from / emerges-from).

Strengths & constraints

Strengths

  • Cross-disciplinary connector — 38% 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 2 foundation relations. structural
  • Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

Concepts

The scientific picture
  • Connects 8 other ideas across 1 discipline.
  • A cross-disciplinary bridge — its connections reach into 4 other fields.
  • Most of its connections are of the “Kind & structure” kind.

Derived from the graph’s real structure — observations, not a score.
