It was first observed on 21 August 2006 by the Siding Spring Survey. On 10 August 2019, the object safely passed 7.4 e6km e6mi off from Earth. With a nearly 18-year observation arc it has a well determined orbit and is not a threat for the foreseeable future. Discovery 2006 QQ 23 was first observed on 21 August 2006 by the Siding Spring Survey, at the Siding Spring Observatory in Australia. Orbit and classification thumb|left|200px|2019 flyby of 2006 QQ 23 at 13.2 lunar distances. 2006 QQ 23 is classified as an Aten asteroid, which means that it is a near-Earth asteroid that crosses Earth's orbit at two points and has an orbital period of less than a year. Because it will come within 0.05 au of the Earth (MOID) and has an absolute magnitude (H) brighter than 22, 2006 QQ 23 is labelled as a potentially hazardous object. With a nearly 18-year observation arc it has a well determined orbit and is not a threat for the foreseeable future. It orbits the Sun at a distance of 0.57–1.03 au in less than 9 months (263 days; semi-major axis of 0.80 au). Its orbit has an eccentricity of 0.28 and an inclination of 3.4° with respect to the ecliptic. The body's observation arc begins with its first observation at the Siding Spring Observatory on 21 August 2006. Close approach in 2019 On 10 August 2019 at 7:23 am UTC, 2006 QQ 23 safely passed 0.04977 au km on from Earth; travelling at around 4.67 km/s km/h on The asteroid was recovered on 14 July 2019, which extended the observation arc from 8 years to 12 years, and therefore it had a very small uncertainty in the 2019 approach. The uncertainty region in the close approach was ±60 km.uncertainty Physical characteristics Based on its absolute magnitude of 19.71, 2006 QQ 23 is estimated to have a diameter of 250–570 metres using an assumed albedo between 0.05 (carbonaceous) and 0.26 (siliceous).
