Two asteroids the size of a skyscraper are approaching Earth

The first asteroid, 2016 CZ31, will fly by our planet at 7 p.m. Eastern Time (11 p.m.

Greenwich). According to NASA, its speed is 55,618 km/h. 

Astronomers estimate that the asteroid has a diameterabout 122 m. This means that it is the same as a 40-story building in height. 2016 CZ31 will fly past our planet at about 2,800 thousand km. This is seven times greater than the average distance between the Earth and the Moon.

According to NASA, this object approaches the Earth every few years, the next time it will happen in January 2028.

And on Saturday, July 30, anotherthe larger asteroid is 2013 CU83. It is approximately 183 m across. The closest distance to the Earth will be 6,960 thousand km. This is about 18 times the average distance between the Earth and the Moon.

The object will move at a speed of 21,168 km/h and will approach Earth at 7:37 pm ET (23:37 GMT).

NASA and other space agencies are closely monitoring thousands of similar near-Earth objects.

Even if the asteroid's trajectory goes far fromEarth, there is a small chance that its orbit may shift. Even such a tiny displacement could potentially lead to a collision with the Earth.
