How often do you think rocks falling from space land on people? Only one case in history has ever been officially confirmed, although others have been reported. On December 30, 1954, a 4 kilogram (kg) or 9 pounds (lb) crashed into the ceiling 34 old Ann Elizabeth Hodge home. The stone bounced off the radio and on her body leaving an enormous bruise the parable of such a small meteorite hitting a person is negligible, but it happens. What if something larger fell to earth, for example, the largest asteroid in the solar system.


Scientists estimated there are now several hundred million asteroids 1m (meter) or 3.3ft (feet) or more in size in the earth's orbit. Every day about 100t (TON) of them in the form of a small grain of sand and small stone penetrate the earth's atmosphere and burn up, leaving a bright trail of about 30 asteroids with a total mass of up to 2000t (TON) fly directly towards earth atmosphere every year. Occasionally their fragments fell to the earth's surface in the form of meteorites. More noticeable meteorites are larger than 20m (meter) or 65.6ft (feet) fell to earth no more in twice every one hundred years the last of these came down in Chelyabingle, Russia in 2013. Once every thousand years like Tunguska meteorite which was like 75m (meter) or 246ft (feet) in size reach the earth surface asteroid measure in more than a 100m (meter) or 328ft (Feet) land here even less often. Once every few thousand years. The most gigantic asteroid whose dimension is access Kilometer or Miles crashed down to our planet earth in every 100 million years, but in this case, they become cause global catastrophe.


In the extinction of species, one of them probably destroys dinosaurs 65 million years ago. If there were no wind, rain and various geological processes on earth. Our entire plant would be dotted with craters has can be seen on the moon or mercury, the reaming traces of space object confirmed asteroids impact are not fantasy at all, the arrival of large stone remains only a matter of time. scientist consider asteroid at least 140m (meter) or 460ft (feet) in size as most dangerous at the same time they're mostly located further than 7.5 million kilometers or 4.6 million miles from the earth however it is very difficult to notice them often poorly reflect sunlight have a flat shape and fly 36,000 km/h or 22,400 mi/h for individual asteroids the speed can be noticeable higher.

Therefore, even the most powerful technology is far from capable of stopping all the most dangerous candidates will approach in October 2028 1997XF11 could ly fly past our planet at the distance of 930,000km (kilometer) or 580,000m (mile) away. This is so close you could watch with ordinary binoculars. The size of an asteroid according to various estimates ranges from 700….1400m (Mile) that is 2,300….4,600ft (feet), scientists claimed that is going to happen.


Suppose something goes wrong, and it changes its course straight for earth. The collision speed of such a block with the surface of the earth would be about 48,300 km/h or 30,000 mi/h this would create an explosion of 1 million MT (Mega Ton) it is hard to imagine such a figure.


Imagine that it partially burn out in the atmosphere or divided into smaller fragments if an asteroid fragment of a one-story house crushes into the earth at the same speed its power approximately comparable bomb detonated in Hiroshima about 20KT (kiloton) such collision would erase every reinforced concrete building with radius 800m (meter) or 2600ft (feet) from the impact of the asteroid. Everything made of wood within a radius of 2.4km (kilometer) or 1.5m (mile) would be destroyed.


If the length of the fallen asteroid incomparable to 20 story building, it's all a little over 60m (meter) or 200ft (feet) wide. The impact power will be close to the explosion of modern nuclear bombs that is approximately 25….50KT (kilo Ton) this is enough to insinuate every reinforced concrete structure within km (kilometer) or 5mi (mile) from the point of impact consequently are living thing on the sight will perish in the event of  1997XF11 forced to earth as a whole the power of the explosion would be X50 million times power detonated in Hiroshima. Everything in the radius of 160…329km (kilometer) or 100….200mi (mile) will be turned to ashes.


If the epicenter were, for example, Newyork city then for Boston to Washington DC there would not be a simple tiny living life. From reaming with exception of super-resistant bacteria. The explosion will raise a tremendous amount of dust into the atmosphere, forming clouds that would block sunlight from the earth's surface. Therefore, anyone who survived is likely to die from a sudden cob snap.


If such an asteroid hits the ocean, it will create enormous waves more than 30m (meter) or 100ft (feet) It will wash away anything on the nearest coast. This asteroid is only one of the few potentially dangerous objects that could destroy life on earth.


The largest and most dangerous is "cares" in 2006, scientist change it statues from an asteroid to dwarf planet, Ceres has a diameter of about 945km (kilometer) or 587mi (mile). Discovery channel employees created an animation showing the effects of a collision between Ceres and earth. According to their video first, the shadow of an impending object would block a very large area of earth from sunlight when it reaches the atmosphere. The asteroid would begin to burn, then ceres would penetrate deep into the plant creating an enormous tsunami. The forces of collision would so powerful that the fragments of the earth would fly straight into space and they would remain there for a long. The resulting stone fragments would rain down on a very large area of our planet the "Himalayas" mountains including the peak of Everest would be completely burned and turn into a plain. Unlikely that anyone would be able to survive on earth after such an impact. Unfortunately in the near future, a clash with ceres is unlikely. However, this hypothetical experiment shows how fragile and vulnerable life on earth is. According to the scientists from "NASA" to destroy all life on the planet a 10km (kilometer) or 6.5mi (mile) asteroid is enough that is almost 95x smaller than Ceres since a collision with a large asteroid will happen sooner or later.


Researcher regular search for ways to avoid such a catastrophe best way to do that is to change the trajectory of an asteroid or destroy in space before it reaches us. For these porpoises, NASA and SpaceX plan to lunch the "DART" spacecraft. Its mission is to collide with the moon of the Didymos asteroid which in October 2022 will be a survival million kilometers from the earth. DART weight is 500kg (kilogram) or 1,100lb (pound) and measure 12.5 meter by 2.4 meter or 41ft by 8ft. The diameter of the moon 150m (meter) or 500ft (feet).


The scientist calculates that the spacecraft and block of stone will collide with the speed of 6km/s or 3.7mi/s. this allows them to determine small collision can affect the orbit of the asteroid in any case. The key thing is that after this experiment Didymos and its moon will not be heading towards earth because their trajectories are currently not in line with our plant.


In truth for each of us, the chances of dying asteroid are pretty small. Their even smaller the probability of given strike by lighting an amounting totally to only 1 into 280,000, But these static apply to the individual.


 If I talk about the plant as a whole then the hazard coefficient increase. Asteroid 2010 RF12 has the highest chance of colliding with earth 1into 16 it could come with 8,700 to 15,000km or 5,400 to 9,300mi from the earth and in 2095 it could even crash into our planet. Fortunately, it's not large enough to lead to a global cataclysm however there are still many other giant boulders in space flying past earth at dangerous proximity.


In your opinion, will technology be able to fully protect us from a collision in the future?
