American astronomers revealed that the sudden observation of the passage of an asteroid the size of a pickup truck just a few days before it passed the Earth, highlights the shortcomings in the ability to predict what could threaten the planet.
Reuters quoted Terek Daly, a planetary scientist at the Johns Hopkins Applied Physics Laboratory, as saying: We do not know where most of the asteroids that could cause local and regional damage are located, as (BU 2023), which passed near Earth last Thursday, is the smallest of a group that includes asteroids with a diameter ranging Between five and 50 metres.
It is difficult to detect objects of this size before they are much closer to Earth, which complicates any efforts to prepare for what could affect a populated area.
For years, the US Aeronautics and Space Administration (NASA) has given priority to detecting asteroids much larger and more threatening to the existence of humanity than the small space rock (BU 2023), which moved 2,200 miles from Earth's surface, a distance closer than some satellites.
According to NASA, the probability that a space rock called a meteorite will collide with the Earth when it enters the atmosphere is relatively low in this range, and this is graded according to the size of the asteroid, as it is estimated that the probability that a rock with a diameter of five meters will target the Earth is once a year, and a rock with a diameter of 50 meters It is once every thousand years, but with the current capabilities, astronomers cannot know when such rocks are heading towards Earth until a few days ago.
