QS Aql is an eclipsing- and a (probably double-lined) spectroscopic binary with a period of 2.5133 days. However, from 1962 to 1968 the period was 2.5134 days. QS Aql is part of the visual double star Kui 93 with mA = 6.5 mag and mB = 6.7 mag or lA:lB = 1.2:1 (0). The system is also detected in X-rays (White & Marshall, 1983).
