Epsilon Aquarii, Latinized from ε Aquarii, is a single star in the equatorial zodiac constellation of Aquarius, located near the western constellation border with Capricornus. It has the proper name Albali , now formally recognized by the IAU. This is a white-hued star that is visible to the naked eye with an apparent visual magnitude of 3.77. Based upon parallax measurements taken during the Hipparcos mission, it is located at a distance of approximately from the Sun with an absolute magnitude of −0.46. The star is drifting closer with a radial velocity of −15 km/s.

This object is an A-type main-sequence star with a stellar classification of A1 V. It is an estimated 388 million years old with a high rate of spin, showing a projected rotational velocity of around 118 km/s. The elemental abundances in the stellar atmosphere are close to solar, with pronounced underabundances of aluminium and strontium. The star has three times the mass of the Sun and about 2.5 times the Sun's radius. It is radiating 138 times the luminosity of the Sun from its photosphere at an effective temperature of 9,622 K.
