24 Aquarii is a triple star[6] system in the equatorial constellation of Aquarius. 24 Aquarii is the Flamsteed designation. The apparent magnitude of this system is 6.66,[2] which, according to the Bortle Dark-Sky Scale, means it is a faint star that is just visible to the naked eye from dark, rural skies. It has an annual parallax shift of 25.08 mas,[1] which is equivalent to a distance of 130 light-years (40 parsecs) from Earth. The system is moving closer to the Earth with a heliocentric radial velocity of −16 km/s.[2]

The calculated orbit of the visual binary has a period of 48.65 years and a large eccentricity of 0.868.[6] The primary, component A, is itself a single-lined spectroscopic binary with a period of 5.8839 days and an eccentricity of 0.071±0.006.[4] One study gives the system a stellar classification of F7 III,[3] suggesting it contains an evolved giant star. Other classifications give classes matching F-type main-sequence stars for components Aa and B.[4]
