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 {{convert|9.852|pc|ly|0|disp=out|abbr=off}} 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. A 2022 study estimated the true mass of HD 183263 c at about {{Jupiter mass|9.31|link=y}} via astrometry, although this estimate is poorly constrained.
