2017 QP1 is a micro-asteroid on an eccentric orbit, classified as near-Earth object of the Apollo group that made a close approach of 0.17 lunar distances from Earth on 14 August 2017 at 21:23 UTC. It was first observed by ATLAS at 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 km/s under the south pole of the Earth.[2][3]
The orbit of 2017 QP1 is extremely eccentric, going from the orbit of planet Mercury out into the asteroid belt, located between Mars and Jupiter.[1]
