How this entity was disambiguated
This entity first appeared as the object of triple T896264 — 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.
Haumea
Haumea is an elongated, fast-spinning dwarf planet in the Kuiper Belt notable for its rapid rotation, ring system, and two known moons.
-
B.
Makemake
Makemake is a large, icy dwarf planet in the Kuiper Belt, known for its extremely cold surface and status as one of the most massive objects beyond Neptune.
-
C.
Quaoar
Quaoar is a large, distant trans-Neptunian object in the Kuiper Belt, notable for its nearly circular orbit and for having a small moon named Weywot.
-
D.
Kuiper Belt objects
Kuiper Belt objects are icy celestial bodies orbiting the Sun beyond Neptune, thought to be remnants from the early solar system and the source of many short-period comets.
-
E.
Eris
Eris is a distant, icy dwarf planet in the outer reaches of the Solar System, notable for its size comparable to Pluto and its role in prompting the redefinition of planetary status.
- 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: Haumea family Description of subject: The Haumea family is a group of trans-Neptunian objects that share similar orbital characteristics and surface properties, believed to be fragments from a past collision involving the dwarf planet Haumea.
