2006 QV 89 - Near - Earth asteroid of the Apollo class, about 30 m in diameter. Opened on August 29, 2006, when the distance from the Earth to the object was about 0.03 a.e. , and the elongation was equal to 150 degrees. The observation arc is short and is only 10 days. Since 2006, the asteroid has not been observed. According to estimates, the asteroid can approach the Earth on September 23–27, 2019 at a distance of 0.04 a.e. [four]

Possible collision with the Earth
2006 QV 89 has a small inclination of the orbit (1.07 °) relative to the ecliptic plane and MOID relative to the Earth about 10,200 km. [1] The position of the Earth in space at this moment is known, but the position of the asteroid at the same moment is determined with low accuracy. Since no asteroid has been observed since 2006 and the observation arc is short, the Sentry Risk Table estimates the probability of an asteroid colliding with the Earth on September 9, 2019 as 1 chance out of 9100. [3] According to the JPL Horizons ephemeris on September 24, 2019, the distance from the asteroid to Earth will be 0.04 a.e. with uncertainty (significance level 3σ) ± 10 million km. [5] NEODyS shows the date of approach on September 23 with a minimum distance of 0.03 AU [6] The European Space Agency website estimates the chance of impact as 1 to 7300 on September 9, 2019. [7]
Monte Carlo simulations using Solex 12 with 1000 model implementations of the asteroid showed that many possible positions of the asteroids intersect with the Earth. [8]
The asteroid will be in a confrontation near the end of July 2019, while it is estimated that the apparent magnitude will be ~ 22. [6]
