Four asteroids of the COLLISION course with Earth – RT World News



This is a scenario made by a Hollywood blockbuster, the asteroid directs itself to Earth and is ready to destroy human existence. To mark the Asteroid Day, here are four space rocks in the course of a collision with our planet.

The United Nations fears that the possibility of shattering an asteroid in a densely populated area is not taken seriously, so it designated June 30 as the International Day of Asteroids to raise awareness of the potentially catastrophic event.

was chosen because the greatest influence of the asteroids in history happened in Tunguska, Russia, that day in 1908, when a huge asteroid exploded and destroyed hundreds of acres of woodland.

In order to mark this event, here are four asteroids that could come out on Earth.

979 XB

With its 900-meter diameter, if this huge rock strikes our planet, the impact will be devastating. Currently it passes through the solar system at nearly 70,000 km / h and reaches almost 30 km closer to Earth every second.

The European Space Agency (ESA) puts it second in its "list of risks" for asteroids near the Earth. The orbit of this small planet is unreliable, but it is expected to have a chance to hit the Earth in the middle of this century.

Experts warn that 1979 XB can suddenly come much closer to Earth, considering only a small change in its orbit. His next predicted approach on Earth will come in 2024. Apophis

Approximately the size of four football pitches, Apophis is in very close orbit to the Earth. It is currently more than 200 million kilometers, but every half kilometer is closer.

He regularly passes the Earth in his orbit, but the latest radar and optical data show that we are near shaving as he runs past our planet at only 30,000 km in 2029. That's less than one tenth of the distance to the Moon.

He will continue to fly from Earth in mid-October this year when he will take us to a safe distance of about 30 million kilometers. If Apophis exploded in the Earth, the impact is estimated to be similar to about 15,000 nuclear weapons that explode at the same time.

2010 RF12

Impact Monitoring System) and the list of risks to the impact of the ESS. It is currently about 215 million kilometers from the Earth and travels at 117,935 km / h.

The danger of this asteroid is not expected to come to the end of the century when it is estimated to be 40 times closer to the Moon. Fortunately, it weighs, relatively little, 500 tons and is about seven meters in diameter. It is assumed that the impact will be a little less than the meteor that hit the Russian city of Chelyabinsk in 2013, damaging thousands of buildings and wounding hundreds of people.

2010 RF12 is set to pass Earth on August 13, 2022, when astronomers around the world will train their telescopes on the site to learn as much as possible about it and its trajectory. 2000 SG344 2000 SG344 is part of a group called Athenian atheroids that have orbits that are very closely related to the Earth. It is foreseen to have a chance of impact over the next three or four decades. With a diameter of only 50 meters, it is relatively small, but it is twice as large as the Chelyabinian meteor, which caused so much damage six years ago.

At present, it travels through more than 112,000 km / h and reaches 1.3 km closer to the Earth every second. Interestingly, he travels around the Sun almost at the same time as the Earth, 353 days versus 365 days on Earth. This gives astronomers regular chances to observe the asteroid and appreciate the risk it creates.

Undetected Asteroids

Of course, much of the danger of dangerous space objects is that we are not good at discovering them, and some of the most dangerous have surprised us. When the Chelyabinsk meteor entered the atmosphere of the Earth unnoticed, its explosion released up to 30 times more energy than the nuclear bombs that the US fell on Japan in 1945

Already in December last year, another asteroid broke over the Bering Sea. times more powerful than the bombs dropped on Hiroshima and Nagasaki. Neither near-ground objects (NEOs) are tracked in advance. We hope that International Asteroid Day will prompt authorities all over the world to improve the way they discover potentially cataclysmic space rocks.
