HR 6135
star in the constellation Apus
HR 6135 is a single star in the southern constellation of Apus, less than a degree from the northern constellation border with Triangulum Australe. Its declination of −70° 59.3′ puts it just within 20 degrees of the southern celestial pole. The star has an orange hue and is faintly visible to the naked eye with an apparent visual magnitude of 5.50, making it the 12th-brightest star in the constellation. It is located at a distance of approximately 1,000 light years from the Sun based on parallax, but is drifting closer with a radial velocity of −9.5 km/s. It has an absolute magnitude of −1.45.
This is an aging bright giant with a stellar classification of K0.5IIbCN1, where the suffix notation indicates an anomalous overabundance of cyanogen in the spectrum. It is a mild barium star, which may indicate it is on the asymptotic giant branch stage of its evolution.
This brief starts where responsible research should: with the source description of “HR 6135” as star in the constellation Apus. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as star in the constellation Apus. Its deeper value depends on whether names, dates, institutions and citations support that framing.
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 Jun 26, 2026. The linked authority identifier is Q10848196. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
