Omega1 Aquarii, Latinized from ω1 Aquarii, is the Bayer designation for a single [6] star in the equatorial constellation of Aquarius. With an apparent visual magnitude of 4.96, [2] this star is faintly visible to the naked eye from the suburbs. The distance to this star can be estimated from the parallax as approximately 138 light-years (42 parsecs). [1]
The stellar classification of this star is A7 IV, [3] matching a subgiant star. It is spinning rapidly with a projected rotational velocity of 105 km/s. [8] The star is about 600 [9] million years old and is radiating 15 [1] times the Sun's luminosity. It has 1.9 [7] times the mass of the Sun and 2.4 [1] times the Sun's radius.
