'''{{mp|2017 QP|1}}''' is a micro-[[Astronomy:Asteroid|asteroid]] on an eccentric orbit, classified as [[Astronomy:Near-Earth object|near-Earth object]] of the [[Astronomy:Apollo asteroid|Apollo group]] that made a close approach of 0.17 [[Astronomy:Lunar distance|lunar distances]] from Earth on 14 August 2017 at 21:23 UTC. It was first observed by [[Astronomy:Asteroid Terrestrial-impact Last Alert System|ATLAS]] at [[Astronomy:Haleakala Observatory|Haleakala Observatory]], Hawaii, on 16 August 2017, two days after its closest approach. The asteroid is estimated to measure between 37 and 83 meters in diameter. It flew past Earth at a speed of 23.97&nbsp;km/s under the south pole of the Earth.<ref name="MPC-object" /><ref name="watchers" />

The orbit of {{mp|2017 QP|1}} is extremely [[Astronomy:Orbital eccentricity|eccentric]], going from the orbit of planet [[Astronomy:Mercury (planet)|Mercury]] out into the [[Astronomy:Asteroid belt|asteroid belt]], located between [[Astronomy:Mars|Mars]] and [[Astronomy:Jupiter|Jupiter]].<ref name="jpldata" />
