HD 200779
astronomical object in the constellation Equuleus
HD 200779 (HIP 104092; Gliese 818; LHS 3624) is a solitary star located in the equatorial constellation Equuleus, the foal. It has an apparent magnitude of 8.27, making it readily visible in binoculars but not to the naked eye. The object is located relatively close at a distance of 49 light-years based on Gaia DR3 parallax measurements, which makes it the nearest star in Equuleus. It is the most distant star that is the nearest in its constellation. It is classified as a high proper motion star, with a total proper motion of 569 mas/yr.
At its current distance, HD 200779's brightness is diminished by only six hundredths of a magnitude due to interstellar dust and it has an absolute magnitude of +7.38. HD 200779 is expected to come within 7.76 parsecs (25.3 ly) of the Solar System in roughly 160,000 years.
HD 200779 is an ordinary K-type main-sequence star with a stellar classification of K6 V. It has 68% the mass of the Sun and 69% of its radius. However, it only radiates 18% the luminosity of the Sun from its photosphere at an effective temperature of 4,406 K, giving it an orange hue. It has an iron abundance slightly above solar level at [Fe/H] = +0.05 and it is estimated to be 6.33 billion years old.
“HD 200779” enters the record as astronomical object in the constellation Equuleus. Crown Archives preserves that source wording while asking what astronomical, object and constellation can confirm, complicate or overturn.
Why this record matters
“HD 200779” is worth following because a concise public description often conceals a longer documentary argument. Here, astronomical, object and constellation 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 12, 2026. The linked authority identifier is Q5174599. 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.
