HD 183263
star in the constellation Aquila
HD 183263 is a star with a pair of orbiting exoplanets located in the equatorial constellation of Aquila. It has an apparent visual magnitude of 7.86, which is too faint to be visible to the naked eye. The distance to this system is 178 light years based on parallax measurements, but it is drifting closer with a heliocentric radial velocity of −50 km/s. Judging from its motion through space, this star is predicted to approach to within 32 light-years of the Sun in around 952,000 years. At that distance, it will be faintly visible to the naked eye.
This is an older star with a spectrum matching a stellar classification of G2 IV, indicating it is about to leave the main sequence after exhausting the supply of hydrogen at its core. It will then evolve into a red giant before dying as a white dwarf. This star has an absolute magnitude (apparent magnitude at 10 pc) of 4.16 compared to the Sun’s 4.83, which indicates the star is more luminous than the Sun, and therefore hotter by about 100 K. At the age of 8.1 billion years, the magnetic activity in its chromosphere is quiet and it is spinning slowly with a rotation period of 32 days.
Planetary system
The star has two known super-jovian exoplanets in orbit around it. Exoplanet b was discovered in 2005 while exoplanet c was discovered in 2008.
Begin with the source’s own compact description: “HD 183263” is star in the constellation Aquila. The dossier treats that line as a proposition to test through star, constellation and Aquila, not as a finished interpretation.
Why this record matters
The phrase “star in the constellation Aquila” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q1563217. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2005 and 2008.
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.
