According to reports from foreign media, 13 years ago, a space rock called 2006 QV89 was disturbed by the close distance of its orbit to Earth, but then the asteroid disappeared.Now astronomers have finally discovered it again and ruled out the possibility that it would hit Earth in the next century.
Asteroid 2006 QV89 was discovered in August 2006, when it passed through the earth and was visible for 10 days. During this time, astronomers carefully mapped its orbit and determined that it had a 1/7000 chance of colliding with Earth in September 2019. After this space rock disappeared without a trace, and this disappearance lasts 13 years.
Now this rock is finally found. On August 11, an observation by the Canada-France-Hawaii Telescope (CFHT) found that QV89 is likely to appear in one of several previously evaluated locations.
Following the announcement, NASA's Jet Propulsion research team and the University of Pisa began calculating the data to obtain the latest QV89 tracking and to check if it still poses a threat to Earth.
The good news is fast coming: the asteroid 2006 QV89 will not hit Earth in the next century.
Of course, the QV89 of 2006 is not the only space rock that could hit Earth. In this regard, NASA and other agencies are paying close attention to thousands of NEOs to take defense measures.
