This is a Hollywood blockbuster script, the asteroid is turning to Earth and is ready to eradicate human existence. To mark the Asteroid Day, here are four cosmic rocks on the road to collision with our planet.
The United Nations fears the possibility of asteroid breaking into a densely populated area is not taken seriously enough, so June 30 is designated as the International Asteroid Day to raise awareness of a potentially catastrophic occurrence.
The date was chosen because the greatest asteroid influence in the recorded history occurred over Tungus in Russia that day in 1908 when a huge asteroid exploded and destroyed hundreds of hectares of forests.
To mark the event, here are four asteroids that could penetrate the Earth.
With its 900 meter diameter, if this huge stone hits our planet, the impact would be devastating. It is currently passing through the Sun's system at almost 70,000 km / h and gets almost 30 km closer to the Earth every second.
The European Space Agency (ESA) put it in second place on its "Risk List" for asteroids near Earth. The orbit of this smaller planet is unreliable, but it is anticipated to have a chance to hit Earth in the middle of this century.
Experts warn that in 1979, XB could suddenly become much closer to Earth, given the small variation in its orbit. The next projected approach to the Earth should come in 2024.
About the size of four soccer fields, Apophis is in a very close orbit with Earth. It is currently more than 200 million miles away, but gets half a mile closer every second.
The Earth is on its orbit regularly, but the latest radar and optical data suggest that we are in close proximity when passing our planet at a distance of only 30,000 km in 2029. It is less than a tenth of the distance from the moon.
The next flight will fly to Earth in mid-October this year when it will take us to a safe distance of about 30 million kilometers. If Apophis hit the Earth, the impact was calculated to be similar to about 15,000 nuclear weapons detonating at once.
This asteroid has the suspicious honor of surmounting the Sentry List and a list of ESA risk impacts. It is about 215 million kilometers from Earth and travels at a speed of 117,935 km / h.
The danger of this asteroid is not expected to reach the end of the century when it is estimated to reach 40 times closer to the moon. Fortunately, she is heavy, relatively small, 500 tons and about seven meters in diameter. The impact is expected to be slightly smaller than the meteorite hit by the Russian city of Chelyabinsk in 2013, which damaged thousands of buildings and injured hundreds of people.
2010 RF12 was set to pass Earth on August 13, 2022, when astronomers around the world will train their telescopes on the facility to find out more about him and his journey.
2000 SG344 is part of a group called Aten Asteroids, and the orbits are very closely related to the Earth. It is anticipated to have a chance to influence the next three or four decades. With only 50 meters in diameter, it is relatively small, but it is still twice as large as the meteorite Chelyabins who six years ago caused so much damage.
It is currently traveling through space at more than 112,000 km / h and every second approaches Earth to 1,3 km. It is interesting to travel around the sun almost at the same time as Earth, 353 days compared to Earth 365 days. This gives astronomers a chance to observe the asteroid and assess the risk it poses.
Of course, much of the danger of dangerous space objects is that we are unable to detect them, and some of the most dangerous have surprised us. When the meteorite Chelyabinsk entered the Earth's undiscovered atmosphere, it exploded up to 30 times more energy than the atomic bombs that the US fell on Japan in 1945.
In December last year, the second asteroid broke through the Bering Sea that was ten times stronger than the bombs that hit Hiroshima and Nagasaki. There were no items near Earth (NEO) in advance. We hope that the International Asteroid Day will inspire authorities around the world to improve the way they discover the potentially cataclysmic cosmic rocks.
