Roche limit
E1125782
UNEXPLORED

How this entity was disambiguated
This entity first appeared as the object of triple T14889678 — 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.
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.
-
B.
Earth–Moon Lagrange region
The Earth–Moon Lagrange region comprises the gravitationally stable and semi-stable points in the Earth–Moon system where spacecraft can maintain position with minimal fuel, making it valuable for observation, navigation, and future space infrastructure.
-
C.
Laplace Gap
The Laplace Gap is a narrow, relatively faint gap within Saturn’s rings, located inside the broader Cassini Division and shaped by gravitational resonances with Saturn’s moons.
-
D.
Encke Gap
Encke Gap is a prominent, relatively wide division within Saturn’s A ring, known for containing several ringlets and small moonlets.
-
E.
Kirkwood gaps
Kirkwood gaps are regions in the asteroid belt with a noticeably low density of asteroids, caused by orbital resonances with Jupiter.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
