Titius–Bode law
E409157
The Titius–Bode law is an 18th-century empirical rule that approximates the distances of planets from the Sun using a simple numerical sequence, historically noted for roughly predicting the positions of several known planets and the asteroid belt.

How this entity was disambiguated
This entity first appeared as the object of triple T4050187 — 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.
Kepler’s laws of planetary motion
Kepler’s laws of planetary motion are three fundamental principles that mathematically describe how planets orbit the Sun in ellipses, sweep out equal areas in equal times, and relate their orbital periods to their distances from the Sun.
-
B.
Laplace resonance
Laplace resonance is a three-body orbital resonance in which the orbital periods of Jupiter’s moons Io, Europa, and Ganymede are linked in a precise 1:2:4 ratio, strongly affecting their dynamics and internal heating.
-
C.
Kirkwood gaps
Kirkwood gaps are regions in the asteroid belt with a noticeably low density of asteroids, caused by orbital resonances with Jupiter.
-
D.
Keppler
Keppler is a German surname most notably associated with Wilhelm Keppler, an industrialist and early economic adviser to Adolf Hitler.
-
E.
Tychonic system
The Tychonic system is a historical hybrid model of the cosmos in which Earth is stationary at the center while the Sun orbits Earth and the other planets orbit the Sun, proposed as a compromise between geocentric and heliocentric theories.
- 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: Titius–Bode law Description of subject: The Titius–Bode law is an 18th-century empirical rule that approximates the distances of planets from the Sun using a simple numerical sequence, historically noted for roughly predicting the positions of several known planets and the asteroid belt.
