"This was a much smaller object than we are tasked to detect and warn about", NASA's Planetary Defense Officer Lindley Johnson said in the statement.
Also, the scientist says that such examples are illustrative of the work of NASA: "This is a real event allows you to test our capabilities and gives some condence that our models predict collisions suited to respond to the potential impact of larger objects". Asteroid 2018 LA was only the third asteroid discovered on an impact trajectory, the agency said, and just the second time a high probability of impact was determined ahead of time.
A faint figure was discovered moving across the sky on Saturday by the Catalina Sky Survey, outside of Tucson, Arizona. This is just the 3 time that the scientists detected an asteroid emerging towards the Earth and having a direct collision event with it.
The Asteroid Belt between Mars and Jupiter contains hundreds of thousands of asteroids more than half a mile in size or more, with millions of smaller objects tumbling in space.
Hours later, it hit Earth travelling at 38,000 mph and caused a huge fireball to appear in the sky above Botswana, Africa.
Meteorites probably reached the floor because the asteroid broke apart, Brown stated. When it reached Earth, the asteroid was traveling incredibly fast, at 10 miles per second. He adds that the event is also only the second time that a location has been identified with enough time before eventual impact. The video was captured at a farm just across the border in South Africa.
As per the calculations of the NEO watchers, the Asteroid entered the atmosphere in the region like Papua New Guinea to the Indian Ocean which is nearer to Africa.
These images show the discovery of asteroid 2018 LA by the Catalina Sky Survey on June 2, 2018.
One such larger object was the asteroid that went completely undetected until it collided with the atmosphere over Russian Federation in 2013, creating a shock wave that blew out thousands of windows in the town of Chelyabinsk ans caused a number of injuries.
Only twice before has a small asteroid been detected hours before colliding with Earth.
On Oct. 7,2008, the 13-foot (4 m) asteroid 2008 TC3 hit Earthover northern Sudan.
The two previous events, over the Sudan in 2008 on October 7, 2008, and over the Atlantic Ocean on January 1, 2014, were also first noticed by the Catalina Sky Survey.
