The dangerous asteroid that has disappeared for a long time is finally found and will not hit the earth – exploration of science – cnBeta.COM



According to foreign media reports 13 years ago, the cosmic rock called QV89 from 2006. It was disturbed by the close distance of its orbit from Earth, but then the asteroid disappeared.Now astronomers have finally discovered it again and ruled out the possibility of hitting it in the next century.

Asteroid 2006 QV89 was discovered in August 2006 when it passed through Earth and could be seen for 10 days. At that time, astronomers carefully mapped their orbit and determined it had a chance of 1/7000 collision with Earth in September 2019. Then this cosmic rock disappeared without a trace, and this disappearance lasts 13 years.

Now this rock has finally been found. An August 11 observation of the Canadian-Franco-Hawaiian Telescope (CFHT) showed that QV89 is likely to appear at one of several previously estimated locations.

Following the announcement of the NASA Jet Propulsion Laboratory and the University of Pisa research team, they began calculating data to obtain the latest pathway QV89 and see if it still poses a threat to Earth.

The good news came quickly: the 2006 QV89 asteroid will not hit Earth in the next century.

Of course, QV89 from 2006 is not the only cosmic rock that can hit Earth. Therefore, NASA and other agencies are paying close attention to thousands of new operators who are undertaking defense activities.
