Almost touched the ground .. Given the meteor, which has not been monitored by scientists (video)

"The meteor came very fast," said a professor at the University of Physics and Astronomy at Monash University, "we only realized that what happened was pbaded after our pbading near the Earth. "

"I was shocked by the fact that this meteorite is probably larger than the meteorites that have approached Earth for many years," the Washington Post reported.

But how did scientists fail to observe it? Professor:

First, because its size is not as big as that of meteorites that can trigger a disaster such as the extinction of dinosaurs.

Second, we rely on the reflected sun. Even when the asteroid "Asteroid 2019 OK" approaches, it is difficult to see with a telescope.

Thirdly, potential operators to determine its earlier position were the "irregular" and elliptical orbits and its speed of 24 km per second, the observed meteorological velocity being between 4 and 19 km per second.

According to scientists, the lack of meteor observation indicates that we know very little about the space and the danger that meteorites represent.
