-
A.
Gliese 581c
Gliese 581c is an exoplanet orbiting the red dwarf star Gliese 581 in the constellation Libra, once considered a potentially habitable “super-Earth” due to its size and location in its star’s habitable zone.
-
B.
Tau Ceti
Tau Ceti is a nearby Sun-like star in the constellation Cetus, notable for its stability, potential planetary system, and historical importance as an early target in the search for extraterrestrial intelligence.
-
C.
Epsilon Eridani
Epsilon Eridani is a nearby young K-type main-sequence star in the constellation Eridanus, notable for its debris disk and status as a prominent target in exoplanet and SETI searches.
-
D.
Aldebaran planetary system
The Aldebaran planetary system is a stellar system centered on the bright orange giant star Aldebaran, located in the constellation Taurus and known to host at least one candidate exoplanet.
-
E.
Epsilon Eridani b

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: Gliese 581 star system Description of subject: The Gliese 581 star system is a nearby red dwarf system in the constellation Libra that gained prominence for its potentially habitable exoplanets and as a target for interstellar messages from Earth.
