66 Aquarii

Star in the constellation Aquarius

Star in the constellation Aquarius

| b-v = +1.376 | u-b = +1.549

66 Aquarii is a single It is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 4.673. Based upon an annual parallax shift of 7.53 milliarcseconds, the distance to this star is about 430 ly.

This is an evolved giant star with a stellar classification of K3 III. It has expanded to 37 times the radius of the Sun and is radiating 434 times the luminosity of the Sun from its outer envelope at an effective temperature of 4,170 K. This gives it the orange-hued glow of a K-type star. It is a suspected variable star that ranges in magnitude between 4.66 and 4.71.
