The earth is the asteroid bigger than the famous Chelyabinsk
NASA
Discovered by astronomers this month EA2 2019 asteroid is approaching the Earth. According to the National U.S. space Agency (NASA), celestial body with a diameter of 39 meters at a speed of 5 km/s will close on March 22 for our planet at the minimum distance, which will be 303733 km, according to CNET. This is less than the distance from the earth to the moon (384467 km).
Danger for earthlings 2019 EA2 is not. Notable is the fact that astronomers can observe quite a large object (the size can almost be twice the asteroid that hit Chelyabinsk oblast in 2013), which was discovered in advance. It is noted that regular smaller celestial bodies carried by and at closer distances to the planet, but are often reported these events after they flew.
Newly-discovered asteroid 2019 EA2 will pass closer than the Moon on 3/21-22. Normally we don’t get over a week of notice for close approachers, but its speed wrt Earth is only ~5 km/s. This slow speed gives Earth the opportunity to bend its orbit.https://t.co/eRix6kTeIv pic.twitter.com/ndBkDY7tlF

Newly discovered asteroid #2019EA2 (diameter ~ 30 m) will have a close encounter with Earth on March 22, 2019 at 01:54 UT flying at a distance of 0.80 LD or ~305,000 km / 189,600 miles) https://t.co/1IqpTS5xIr pic.twitter.com/DYLMg0Z82O

“This phenomenon is absolutely safe. If you already have to thousands of miles distance is defined, it [the asteroid], just fly past at a distance of 300 thousand kilometers,” – said the Agency TASS, the astronomer-observer of the Tomsk planetarium Evgeny Parfenov.
However, he added that if the scientists were wrong, and the asteroid hits the planet, then it is hoped that he will fly past cities. “When he fell down the famous Chelyabinsk meteorite, povyshibalo glass houses. According to official figures, affected 1.5 thousand people – they watched it fall standing at the window and suffered from splinters when glass knocked out by the shock wave. Here the wave will be such that will not hurt glass, and entire buildings. But if he will fly into the wilderness, no one will even notice” – said Parfenov.
In the Solar system moved a huge number of comets and asteroids. The majority of them (98%) concentrated in the main asteroid belt (located between the orbits of Mars and Jupiter), the Kuiper belt and the Oort cloud (the existence is confirmed only indirect evidence).
Occasionally some facilities of these areas as a result of clashes with neighbors and/or under the influence of gravity, larger objects leaving the usual orbit and can be directed, including the Earth, says Wikipedia.
As explained TASS news Agency Professor, Department of physical techniques and devices for quality control, Ural Federal University (Urfu), the Chelyabinsk meteorite researcher Viktor Grokhovsky, who is controlling the scientific community is approximately 20 thousand asteroids that approach the Earth and traverse her orbit. This phenomenon cannot be seen with the naked eye, however, there are machines and stations, watching the approaching asteroids.
Best known in recent years was the fall of the meteorite 15 February 2013 in Chelyabinsk region. The size of the asteroid was about 19.8 meters in diameter and weight is 13 tons. Then injuring about a thousand inhabitants. 16 Oct largest fragment of the meteorite weighing about 600 kg was raised from the mud at the bottom of lake Chebarkul with a depth of approximately 20 meters.
