Lissajous orbit

E290066

orbit type spaceflight trajectory

A Lissajous orbit is a stable, looping three-dimensional trajectory around a Lagrange point, commonly used by space observatories to maintain a relatively constant position with respect to Earth and the Sun.

How this entity was disambiguated

This entity first appeared as the object of triple T2705991 — 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.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Lissajous orbit
Context triple: [Sun–Earth L2, typicalOrbit, Lissajous orbit]

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. Orbit
Orbit is a publishing imprint best known for releasing science fiction and fantasy books.
C. Orbit
Orbit is the fuzzy green alien mascot of the Houston Astros, known for his playful antics and fan-friendly entertainment at the team’s baseball games.
D. Sun–Earth L1 Lagrange point
The Sun–Earth L1 Lagrange point is a gravitationally stable location between the Earth and the Sun where spacecraft can maintain a relatively fixed position with minimal fuel, ideal for continuous solar and space weather observations.
E. Sun–Earth L2
Sun–Earth L2 is a gravitationally stable point in space located beyond Earth's orbit where the combined gravity of the Sun and Earth allows spacecraft, such as the James Webb Space Telescope, to maintain a relatively constant position with minimal fuel use.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
