How this entity was disambiguated
This entity first appeared as the object of triple T6236470 — 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.
Newtonian celestial mechanics
Newtonian celestial mechanics is the classical theory that uses Newton’s laws of motion and universal gravitation to predict and explain the motions of celestial bodies such as planets, moons, and comets.
-
B.
Mécanique céleste
Mécanique céleste is Pierre-Simon Laplace’s landmark multi-volume treatise that reformulated celestial mechanics using Newtonian gravitation and advanced mathematical analysis, profoundly shaping modern astronomy and physics.

C.
Division on Dynamical Astronomy
The Division on Dynamical Astronomy is a specialized branch of the American Astronomical Society focused on the study of the motions and gravitational interactions of astronomical objects.
-
D.
Gauss’s planetary equations
Gauss’s planetary equations are a set of differential equations in celestial mechanics that describe how a planet’s orbital elements change over time under the influence of perturbing forces.
-
E.
Lagrange’s planetary equations
Lagrange’s planetary equations are a set of differential equations in celestial mechanics that describe how the orbital elements of a body evolve over time under perturbing forces.
- 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
