We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

TRAPPIST-1 system — The distance is given as 40.7 light-years, but the widely accepted distance is about 39.5 light-years (12.1 parsecs).
TRAPPIST-1 system — The star's surface temperature is listed as 2,550 K, but the commonly cited value is around 2,511 K (with some variation, but 2,550 K is not standard).
Kepler-452b — The entry states 'Kepler-452b (also known by its Kepler object of interest designation KOI-7016.01)'. The correct KOI designation is KOI-7016.01, but the planet's official Kepler designation is Kepler-452b, not KOI-7016.01 (the KOI designation is for the candi
Kepler-452b — The entry says 'The SETI Institute scanned Kepler-452b for radio transmissions using the Allen Telescope Array after the discovery announcement, covering over 2 billion frequency bands, though the observations were not completed by July 2015.' This implies the
51 Pegasi b — The LORE section states the planet was confirmed by another team using the Lick Observatory within a week, but the Lick team's confirmation was not within a week of the original announcement.
51 Pegasi b — [contradicted] The planet's discovery was announced at a conference on October 6, 1995, and published in the journal Nature on November 23, 1995 :: The source says the discovery announcement was on October 6, 1995, in the journal Nature, with no mention of a c
Proxima Centauri b — [staleness sweep] contains time-sensitive marker (As of 2023) - verify against current source and re-date or remove
Kepler-22b — [staleness sweep] contains time-sensitive marker (as of 2023) - verify against current source and re-date or remove
Kepler-22b — [contradicted] Its radius was initially thought to be 2.4 times that of Earth but was revised to 2.1 Earth radii as of 2023 :: The source states 'Kepler-22b's radius was initially thought to be 2.4 times that of Earth, but has since been revised to 2.1 R🜨 as o
The habitable zone — [staleness sweep] contains time-sensitive marker (As of 2013) - verify against current source and re-date or remove
HD 189733 b — [contradicted] First exoplanet to have its thermal map constructed :: the source says "HD 189733 b was also the first exoplanet to have its thermal map constructed" — this matches, but the claim is correct. Actually no contradiction. Re-evaluating: No contradi
HD 189733 b — [contradicted] Very dry atmosphere announced in July 2014 :: the source says "In July 2014, NASA announced the discovery of very dry atmospheres on three exoplanets... HD 189733 b, HD 209458 b, and WASP-12b" — this matches.
K2-18b — [contradicted] K2-18b receives about the same amount of light from its star as Earth receives from the Sun. :: The source states it receives "approximately a similar amount of light as the Earth receives from the Sun" and "Incoming stellar radiation amounts to
K2-18b — [contradicted] The planet has a density intermediate between Earth and Neptune, about 2.67 g/cm³. :: The source states "The density of K2-18b is about 2.67+0.52−0.47 g/cm3—intermediate between that of Earth and Neptune." — no contradiction.
