2016 PQ
2016 PQ is an approximately 20-meter sized asteroid and near-Earth object of the Apollo group, with one of the smallest known minimum orbital intersection distances with Earth.
Discovery
The asteroid was discovered by the Pan-STARRS telescope on 2 August 2016, when it had reached magnitude 20.5, and it had brightened by magnitude 19.0 three nights later, after which it became too close to the Sun to spot with ground-based telescopes. It reached its closest approach to the Earth on 7 August 2016, at 0.025 AU, or 9.8 lunar distances.Orbit
orbits the Sun at a distance of 0.9–2.9 AU once every 2 years and 8 months. Its orbit has an eccentricity of 0.54 and an inclination of 3° with respect to the ecliptic.MOID
has a very small minimum orbit intersection distance to the Earth only around, corresponding to 0.038 lunar distances or 2.3 Earth radii. It has the 19th lowest MOID of any known asteroid, as well as the 7th lowest MOID of any object larger than it.Despite its very low MOID, it is not on the Sentry Risk Table, as it is not going to make any nearby close approaches to Earth in the near future. It is too small to be classified as a potentially hazardous asteroid.
