2006 QQ23[a] is a sub-kilometre asteroid, classified as a near-Earth object of the Aten group that is potentially hazardous only as the orbit evolves over millennia. It was first observed on 21 August 2006 by the Siding Spring Survey.[1][2] On 10 August 2019, the object safely passed 7.4 million kilometres (4.6 million miles) from Earth.[5][6] With a 12 year observation arc it has a well determined orbit and is not a threat for the foreseeable future.[5]
