ChaHα8
star in the constellation Chamaleon
ChaHα8 (also written ChaHa8 when Greek letters are unavailable) is a binary brown dwarf about 640 light-years (200 parsecs) from Earth in the constellation Chamaeleon. The designation indicates that it is in the Chamaeleon I star-forming region and that it displays hydrogen-alpha emission. It was discovered in 2000.
It was found in 2007 to have a low-mass substellar companion in orbit around it via radial velocity observations. The companion has a mass of 25–31 Jupiter masses, and the pair orbit each other with a period of 5.2 years and an eccentricity of 0.59.
“ChaHα8” enters the record as star in the constellation Chamaleon. Crown Archives preserves that source wording while asking what ChaHα8, star and constellation can confirm, complicate or overturn.
Why this record matters
“ChaHα8” is worth following because a concise public description often conceals a longer documentary argument. Here, ChaHα8, star and constellation provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 9, 2026. The linked authority identifier is Q5065918. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2000 and 2007.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
