41 Aquarii is a double star[1] in the equatorial constellation of Aquarius. 41 Aquarii is its Flamsteed designation. It is visible to the naked eye as a dim, orange-hued point of light with a combined apparent visual magnitude of 5.354.[2] The pair are located at a distance of around Шаблон:Convert from the Sun based on parallax, but are drifting closer with a radial velocity of –25 km/s.[3]

The brighter component of the pair is a red clump[4] giant star with a stellar classification of K0 III[1] and a magnitude of 5.73. This is an aging star that has exhausted the supply of hydrogen at its core and is now generating energy through core helium fusion. It has eight[3] times the girth of the Sun and is radiating 34[3] times the luminosity of the Sun at an effective temperature of 4,750 K.[5]

At an angular separation of 5.148 arcseconds, the fainter companion is an F-type main sequence star with a magnitude 7.16 and a classification of F8 V.[1] It has 1.8[6] times the Sun's radius and is radiating six[6] times the Sun's luminosity from its photosphere at 6,899 K.[6]
