Kepler-410
Binary star system
Kepler-410 is a binary star system. Its primary star, also known as Kepler-410A, is a F-type subgiant star, orbited by the orange dwarf star Kepler-410B on a wide orbit. The companion star was discovered in 2012.
The primary star's surface temperature is 6325±75 K. HD 175289 is similar to the Sun in its concentration of heavy elements, with a metallicity Fe/H index of 0.01±0.10, but is much younger at an age of 1.81±0.27 billion years.
Planetary system
In 2013, one planet, named Kepler-410Ab, was discovered using the transit method. It is not known if the planet is orbiting the primary or secondary star. If orbiting the secondary, the planetary radius must be doubled. Immediately, a second non-transiting planet was suspected due to transit-timing variations, and a 2019 study also found evidence for such a planet, though it has not yet been confirmed or given any designation.
Begin with the source’s own compact description: “Kepler-410” is binary star system. The dossier treats that line as a proposition to test through Kepler-410, Binary and star, not as a finished interpretation.
Why this record matters
The phrase “binary star system” 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.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q88345986. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2012, 2013 and 2019.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
