The fast asteroid flew past Earth dangerously close in the early hours of September 9th. NASA has estimated that the rock is closest to Earth around 8.13pm BST (7.13pm UTC). The asteroid takeoff was monitored by NASA's CNEOS at the California Institute of Technology. NASA's CNEOS tracks all asteroids and comets that threaten to strike the Earth.
The asteroid named by NASA Asteroid 2019 RG2 is a half-object of the Apollo type, or
Apollo asteroids fly around the inner rings of a solar system in a trajectory similar to Asteroid 1862 Apollo.
NEOs, on the other hand, are all comets and asteroids orbiting the Earth.
Sometimes a NEO like RG2 will catastrophically cross paths with our home planet.

NASA said, "As they orbit the Sun, near-Earth objects can sometimes get close to Earth.
"Keep in mind that a 'near' astronomical passage can go very far in human terms: millions or even tens of millions of kilometers. ”
The US Space Agency estimates that the RG2 asteroid measures anywhere in the range of 29 feet to 65.6 feet (8.9 meters to 20 meters).
When 65.6 feet (20 m. Scale exploded over Russia's Chelyabinsk region in 201

The cosmic rock closed on Earth at dawn at speeds of about 21.99 km per second or 49.190 km / h.
In its closest approach, the asteroid almost missed Earth from a distance of approximately 0.00350 astronomical units (au).

An astronomical unit measures the distance from Earth to the Sun, or about 93 million miles (149.6 million km).
The distance is 1.36 times the distance from Earth to the moon – an incredibly close brush with the rock.
After last night's glamor, NASA does not expect the space rock to make another appearance around Earth for the foreseeable future.
