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.

Acrux — The entry states Acrux is 'the most southerly star of the asterism known as the Southern Cross' — this is incorrect; the most southerly star of the Southern Cross is Gamma Crucis (Gacrux), not Acrux.
Acrux — The entry says the system was 'the second ever to be recognized as a binary, in 1685 by a Jesuit priest' — this is incorrect; Acrux was not the second binary recognized, and its binary nature was discovered later than 1685.
Algol — The entry states the distance is 94 light-years, but the widely accepted distance is approximately 93 light-years.
Algol — The entry states 'In 1881, the Harvard astronomer Edward Charles Pickering presented evidence that Algol was actually an eclipsing binary.' This is incorrect: Pickering suggested it in 1880, and definitive evidence was provided by Vogel in 1889.
Asteroseismology — The claim that 'modes can only be detected up to an angular degree of about 3 in intensity and about 4 if observed in radial velocity' is inaccurate as a general limit; modes with much higher angular degrees are detected in helioseismology and space-based miss
Asteroseismology — The claim that 'Cepheid variables are core-helium burning stars with masses above about 5 solar masses' is factually incorrect; classical Cepheid variables have masses generally in the range of about 3 to 20 solar masses, with a lower limit around 3–4 solar ma
Beta Centauri — The entry states the spectral type is B1 for all three components, but component B is actually a B-type star with a spectral type of B2V, not B1.
Beta Centauri — The entry says the system's combined magnitude of 0.61 varies by a few hundredths, but Beta Centauri is a known Beta Cephei variable with a magnitude range of about 0.61 to 0.66, which is more than a few hundredths and is noticeable to experienced observers un
Beta Pictoris — The claim that Beta Pictoris c is 'currently the closest extrasolar planet to its star ever photographed' is inaccurate; planets in the TRAPPIST-1 system and other directly imaged planets are closer.
Beta Pictoris — The claim that 'Material from the Beta Pictoris debris disk is thought to be the dominant source of interstellar meteoroids in the Solar System' is not established in mainstream astronomy.
Black dwarf — The claim that 'various white dwarfs cooled below 3900 K were found in 2012 by astronomers using MDM Observatory's 2.4 meter telescope, estimated to be 11 to 12 billion years old' is not a verifiable canonical fact and appears to be invented or misattributed.
Blue giant — The entry states 'The hottest stars, blue horizontal branch (BHB) stars, are called extreme horizontal bra' — this is an incomplete sentence and misrepresents the term; the correct term is 'extreme horizontal branch (EHB) stars', not 'extreme horizontal bra'.
Blue giant — The entry says 'absolute magnitudes around 0 or brighter' — this is too vague and potentially misleading; blue giants can have absolute magnitudes much brighter than 0 (e.g., -5 or brighter), so 'around 0 or brighter' is not accurate for all blue giants.
Blue supergiant — The entry states blue supergiants are above and to the right of the main sequence on the HR diagram, but they are above and to the left; 'blue giant branch' is not a standard term.
Blue supergiant — The entry claims blue supergiants are more common than their main-sequence counterparts, which is false because the supergiant phase is short-lived.
