The 10-story house meteorite suddenly grazed the Earth

Scientists only discovered a large meteorite just 24 hours before it grazed the Earth.

The 2017 AG13 meteorite is 25-35m high, is equal to a 10-storey building, first discovered on the evening of January 8 through the Catalina Sky Survey program of the University of Arizona, USA, according to News.com.au . In the nearest position, 2017 AG13 is only 193,000km from Earth, double the distance between Earth and Moon. This meteorite moves at a speed of 16km / sec.

"2017 AG13 moves very fast, very close to us. It has elliptical orbits and traverses the orbit of two planets, Venus and Earth , " Eric Feldman, astronomer at the astronomical site Slooh. , said.

According to Feldman, 2017 AG13 is about the same size as the meteorite that exploded in the sky of Chelyabinsk, Russia, 2013. The explosion broke glass windows and caused minor damage to buildings in large areas. More than 1,000 people were injured due to fragments.

The next time near the Earth of the meteorite 2017 AG13 is December 28. If it passes through the Earth's atmosphere, this asteroid will explode with a force of 700 kiloton.

Meteors vary in size, brightness and orbit, so many objects are difficult to detect and track. They can reach a diameter of several meters to several kilometers, made up of ice, dirt or metal.

The Planetary Society says only 60% of objects near Earth are more than 1.5 km recognized. The number of smaller objects is many times larger. On average, 5 new meteors are discovered every day.
