Aquarius is an equatorial constellation of the zodiac, between Capricornus and Pisces. Its name is Latin for "water-carrier" or "cup-carrier", and its old astronomical symbol is (♒︎), a representation of water. Aquarius is one of the oldest of the recognized constellations along the zodiac (the Sun's apparent path). [2]
LL Aquarii is an eclipsing binary star system in the equatorial constellation of Aquarius, abbreviated LL Aqr.At peak brightness it has a combined apparent visual magnitude of 9.23, [1] which is too dim to be visible to the naked eye.
Visual observations are difficult and rare. [16] The central region of the jet shows an ejection that took place around 190 years ago, as well as much younger structures. [17] The giant primary star is a Mira variable, a star that pulsates and changes temperature, leading to very large visual brightness changes. The total range of 5.2 - 12.4 is ...
Lambda Aquarii, informally known as Hydor (/ ˈ h aɪ d ɔːr /), [12] [13] is a variable star in the equatorial constellation of Aquarius. The name is Latinized from the Bayer designation λ Aquarii. The apparent visual magnitude of this star ranges from 3.57 down to 3.80, [3] which is bright enough to be

Zeta Aquarii (ζ Aquarii, ζ Aqr) is the Bayer designation for a triple star system, [7] the central star of the "water jar" asterism [9] in the equatorial constellation of Aquarius. The combined apparent visual magnitude of this system is 3.65, [2] which is readily visible to the naked eye.
Alpha Aquarii, officially named Sadalmelik (/ ˌ s æ d əl ˈ m ɛ l ɪ k /), [15] is a single yellow supergiant star in the constellation of Aquarius.The apparent visual magnitude of 2.94 [2] makes this the second-brightest star in Aquarius.
The star has 2.7 [7] times the mass of the Sun and double the Sun's radius. [8] It is radiating 63.5 [ 7 ] times the luminosity of the Sun from its photosphere at an effective temperature of 10,617 K. [ 7 ] When examined in the infrared band, it displays an excess emission that is a characteristic of stars with an orbiting debris disk .
