What it is Filled
A planet proposed to exist but not confirmed or later disproved, such as Vulcan inside Mercury orbit, the disrupted Phaeton, the impactor Theia, counter-Earth and the proposed Planet Nine in the outer solar system, as well as exoplanet candidates awaiting confirmation; fictional planets are a separate category.
Why it exists Filled
Let an agent handle hypothetical planets by proposal, evidence, status and history, attributing claims to their proponents and separating fiction.
Distinguishing features Filled
- Proposed existence
- Status open or disproved
- Based on indirect evidence
- Often controversial
What robots and AI may and may not do Filled
Must not
- Present an unconfirmed planet as real.
- Spread doomsday claims about hidden planets colliding with Earth.
- Misattribute proposals or discoveries.
Only with a human decision
- Announcing a candidate planet as confirmed.
May
- Describe hypothetical planets and the evidence for and against them.
- Mark each one as proposed, disproved or a candidate, citing sources.
Moral aspects Filled
- False planet scares cause real fear, especially among young people.
Who is affected
- The public
- Students
- Researchers
Owners Filled
Steward
Nobody: hypotheses held in common by the scientific community.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.hypothetical-planet
- Wikidata: Q1974542 (https://www.wikidata.org/wiki/Q1974542)
Direct properties required Filled
- Proposed mass: kg - Mass is constrained through dynamical models or observational limits, with estimates remaining conditional on the proposed body's existence.
- Proposed radius: km - Radius is inferred from candidate observations or physical models and must be distinguished from a confirmed measurement.
- Proposed orbital period: days - Orbital period is estimated from candidate orbital solutions or assumed orbital parameters and the mass of the central body.
Recognition required Filled
- Proposed but unconfirmed planets
- Historical predictions such as Vulcan
- Confirmed exoplanets are observed
- Not observed or not confirmed; appears in models, predictions and historical records.
Capabilities and actions required Filled
- explain why a planet was proposed
- report its current status with sources
- summarise searches and evidence
- separate fictional planets
Hazards and failure modes required Filled
- Presenting proposals as discoveries
- Pseudoscientific doomsday claims such as Nibiru
Standards and interfaces required Filled
- IAU planet definitions
- Exoplanet confirmation criteria of catalogues
Context of use required Filled
- History of astronomy and current research questions.
- disproved historical planets
- proposed outer solar system planets
- hypothetical impactors
- exoplanet candidates
- hypothetical planet classes
Sources Filled
- Wikidata item Q1974542: hypothetical planet - identity and sense of the item
- Wikipedia: Hypothetical planet - general description of the item
Open questions
- Should each proposal be a separate entry?
- How should status changes be tracked?
- How should fiction be split off?
