According to NASA, the asteroid was determined to be on a collision course with Earth, with impact just hours away.

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". According to NASA, the impact created a bright fireball in the sky at about 6:44 p.m. local Botswana time (12:44 p.m. ET). There was instant chaos amongst the people as it indicated a big disaster if the asteroid had hit the surface of the earth.

And Second, these tiny asteroids are usually identified only when they enter our air, picked up from the worldwide Monitoring System, a portion of an organization made to track infrasound - or even low-frequency noise waves - at the air.

Four images of asteroid 2018 LA, captured by Catalina Sky Survey telescopes on June 2, 2018.

Initial estimates had the impact zone stretching from southern Africa across the Indian Ocean into New Guinea. Dell'Antonio said if it was daytime, the survey wouldn't have seen it, so it was a lucky coincidence it was spotted.

But smaller asteroids which could wipe out a city might only be detected hours or days before they smash into our planet.

European Trade Commissioner Cecilia Malmstrom said on Monday that preliminary "safeguard" measures for steel could come as early as July.

And While 2018 LA was detected soon before it came at our setting, there are various organizations looking for potentially hazardous asteroids (PHAs) which may seriously affect life.

Regarding the late detection of the asteroid, the CAS explained that because it is a small rock that can be dark, and that because it does not emit its own light, an asteroid like 2018 LA only becomes visible when it is already very close. The asteroid was estimated at just six feet (1.8 metres) across, otherwise known as boulder-sized, NASA's Jet Propulsion Laboratory said in a statement.

Over the weekend, a small asteroid was detected shortly before entering Earth's atmosphere, where it appeared as a giant fireball.

This is the incredible moment a high-speed asteroid the size of a auto explodes over the South African wilderness just seconds before impact. The Catalina Sky Survey has been responsible for discovering all three of these small asteroids on impact trajectories, and all on the watch of the same observer, Richard Kowalski.

The 2008 asteroid was spotted 19 hours in advance and measured 13 feet, or 4 meters.
