HD 134606
star in the constellation Apus
HD 134606 is a yellow-hued star with a planetary system, positioned in the southern constellation of Apus. It is below the nominal limit for visibility with the naked eye, having an apparent visual magnitude of 6.86. Based upon an annual parallax shift of 37.3 mas, it is located 87.44 light-years away. The star appears to be moving further from the Earth with a heliocentric radial velocity of +1.9 km/s.
This is an evolving G-type subgiant star with a stellar classification of G6 IV and is not considered magnetically active, having a chromospheric activity index of −5.04. It has about the same mass as the Sun but is 25% more luminous. The photosphere is radiating energy at an effective temperature of 5,614 K. It has a higher than solar metallicity – a term astronomers use to describe the abundance of elements other than hydrogen and helium.
There is a companion star of spectral type M3V at a separation of ~1500 AU, designated L 72-1. Analysis of its light curve indicate it is itself a close binary.
Planetary system
The discovery of a planetary system orbiting HD 134606 was announced in 2011, following an eight-year survey carried out at the La Silla Observatory in Chile.
“HD 134606” enters the record as star in the constellation Apus. Crown Archives preserves that source wording while asking what star, constellation and Apus can confirm, complicate or overturn.
Why this record matters
“HD 134606” is worth following because a concise public description often conceals a longer documentary argument. Here, star, constellation and Apus provides the most credible route into that argument.
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 13, 2026. The linked authority identifier is Q22086879. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1500 and 2011.
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.
