How many celestial objects are threatening the Earth?
Experts at NASA claimed they had counted nearly all of the celestial bodies that could endanger our planet.

More than a year ago, the WISE infrared telescope scanned the outer space and thanks to the 'optical eye' it saw ' the darkest, most difficult to detect objects.
According to astronomers, around our planet there are no less than 1,000 celestial bodies with a diameter of more than 1 kilometer, but only half of them reach the Earth.
Among celestial bodies ranging in size from 100 meters to 1 kilometer, according to the latest figures, around our planet has 19,500 celestial bodies, not 35,000 as previously calculated.
However, scientists reminded to still need to study more thoroughly to classify and determine which celestial bodies can collide with the Earth, how dangerous they are and more realistic. discuss, propose scenarios to prevent. For example, breaking them from afar, deflecting their direction, even with small, harmless objects that can be used .
The tool that helps astronomers find the most effective astronomical objects today is the NEOWISE telescope. It is the acronym for NEO (Near Earth Object), and WISE for the name of the telescope.
The price of the WISE telescope was launched into orbit around the Earth in 2009 to $ 320 million.
