The asteroid, named NASA Asteroid 2006 QV89, flew past Earth in an approaching trajectory. NASA said the space rock closed at Earth's location today (Friday, September 27). In its closest approach to our home planet, the asteroid arrived at about 4.54 hrs BST (3.54 hrs UTC). When that happened, NASA said the asteroid flew at about 4.13 km per second or 9.238 mph.
What do we know about Asteroid 2006 QV89?
Asteroid 2006 QV89 was first observed flying around the solar system 13 years ago, on August 29, 2006.
At that time, the asteroid was too weak and too small to be properly observed.
The initial uncertainty surrounding its orbit suggested that there was a chance of one-7,000 on the rock hitting Earth.
After the discovery, astronomers made an additional 76 observations to determine the speed, size and trajectory of QV89.

The European Space Agency (ESA) said: "Asteroids come and go, quite literally, often frustrating astronomers.
"You may notice an invading cosmic rock, make some measurements to narrow its orbit, and days later it has disappeared ̵
According to the NASA's Center for Near-Earth Object Studies, the QV89 is a small NEO of the Apollo or near-Earth object type.
NEOs are comets and asteroids flying around the inner solar system that sometimes cross paths with Earth's orbit.

Apollo rocks are asteroids that cross the orbit of Asteroid 1862 Apollo.
The asteroid measures anywhere in the range of 75.5 feet to 170.6 feet (23 meters to 52 meters) through
At the top of the NASA estimate, the asteroid is comparable in size to the Nelson Column in Trafalgar Square, London.
At the lower end of the size estimate, the space rock is about twice as long as the London double-decker bus.

Was there a risk for the 2006 Asteroid QV89 to hit the planet today?
Despite the initial uncertainty over the trajectory of the asteroid 13 years ago, astronomers today have been able to map the orbit of the cosmic rock.
ESA "New observations made with the Canada-France-Hawaii Telescope on August 10-11 revealed the true position of the asteroid, excluding any potential threat to Earth's impact from 2006 QV89 for the next century."
the asteroid approached Earth today from a safe distance of about 0.04631 astronomical units (au).
The astronomical unit is the distance between our planet and the sun – 93 million miles (149.6 million km).
In other words, the asteroid QV86 dropped us from safe dis Tans over 6.3 million miles (6.9 million km).
