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 Script error: No such module "val". and Script error: No such module "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 Script error: No such module "convert". from Earth.
