LHS 1678
star
LHS 1678 (TOI-696) is an astrometric binary star system, located about 65 light-years (19.9 parsecs) from the Earth in the constellation Caelum. It is made up of a red dwarf and a companion star whose nature is still uncertain, but is likely to be a brown dwarf. The red dwarf star is known to host three small, close-in exoplanets.
Characteristics
LHS 1678 is a binary star, more precisely an astrometric binary. It is made up of a red dwarf star and a likely brown dwarf star. They are sometimes called LHS 1678 A and B, respectively. The projected separation of the system, i.e. the observed separation between both stars, is a maximum of 5 astronomical units (750,000,000 km). The orbit is expected to be highly inclined, and the orbital period is on the order of decades, with two possible values of 42 and 100 years, as well as semi-major axes of 36 and 210 AU respectively.
The system is located in the southern celestial hemisphere, within the constellation Caelum.
Begin with the source’s own compact description: “LHS 1678” is star. The dossier treats that line as a proposition to test through star, not as a finished interpretation.
Why this record matters
The phrase “star” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q88314557. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1678.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
