24 Aquarii (abbreviated 24 Aqr) is a double star in the equatorial constellation of Aquarius. 24 Aquarii is the Flamsteed designation. The apparent magnitude of this system is 6.65,[3] 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 22.74 milliarcseconds, which is equivalent to a distance of {{Convert|143|ly|pc|abbr=off|lk=on}} from Earth. The system has a stellar classification of F7 III,[4] suggesting it contains an evolved giant star.
