Script error: No such module "Check for unknown parameters".

107 Aquarii (abbreviated 107 Aqr) is a double star in the equatorial constellation of Aquarius. 107 Aquarii is the Flamsteed designation, although it also bears the Bayer designation i² Aquarii. The pair have an angular separation of 6.787 arcseconds.^[3] They have a combined apparent visual magnitude of +5.305,^[2] with individual magnitudes of 5.72 and 6.72.^[3] The annual parallax shift measured for the two components is Template:Val and Template:Val respectively, although with significant statistical margins of error and flags for potential unreliability of both values. This indicates the system may be at a distance of Template:Convert from Earth.
