How this entity was disambiguated
This entity first appeared as the object of triple T2746778 — 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.

Target entity: Earth-trailing orbit (STEREO-B) Context triple: [STEREO mission, spacecraftOrbit, Earth-trailing orbit (STEREO-B)]
-
A.
STEREO mission
The STEREO mission is a NASA-led solar observatory project using twin spacecraft to provide stereoscopic views of the Sun and its coronal mass ejections, improving understanding and forecasting of space weather.
-
B.
Deep Space Climate Observatory
The Deep Space Climate Observatory (DSCOVR) is a NOAA and NASA satellite positioned at the Sun–Earth L1 Lagrange point that continuously monitors solar wind conditions and provides real-time space weather and Earth observation data.
-
C.
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.
-
D.
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.
-
E.
Lissajous orbit
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.
- 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: Earth-trailing orbit (STEREO-B) Description of subject: Earth-trailing orbit (STEREO-B) is the heliocentric path followed by NASA’s STEREO-B spacecraft as it slowly lags behind Earth to provide a unique vantage point for stereoscopic observations of the Sun.
