How this entity was disambiguated
This entity first appeared as the object of triple T11377021 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

-
A.
Gliese 581d
Gliese 581d is a potentially rocky exoplanet orbiting the red dwarf star Gliese 581, once considered one of the first known candidates for a habitable world outside our solar system.
-
B.
Gliese 581e
Gliese 581e is a low-mass exoplanet orbiting the red dwarf star Gliese 581, notable as one of the smallest exoplanets discovered around a main-sequence star at the time of its detection.
-
C.
Gliese 581c
Gliese 581c is an exoplanet orbiting the red dwarf star Gliese 581 in the constellation Libra, once considered a potentially habitable “super-Earth” due to its size and location in its star’s habitable zone.
-
D.
Gliese 581b
Gliese 581b is a massive, close-orbiting exoplanet in the Gliese 581 system, notable as one of the early and well-studied planets discovered around a red dwarf star.
-
E.
Kepler-186f
Kepler-186f is an Earth-sized exoplanet located in the habitable zone of its red dwarf star, notable as one of the first potentially Earth-like worlds discovered outside our solar system.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Gliese 581f Description of subject: Gliese 581f is a proposed exoplanet orbiting the red dwarf star Gliese 581, once considered a potentially habitable world but whose very existence remains unconfirmed and debated.
