An asteroid is a rocky object that roams about in the outer space and might collide with the planets on it’s way. Such events of collision do not occur too frequently but are not uncommon either. Though, as estimated by studies, only three percent of the actual asteroids hitting the Earth are able to cause massive destruction and crater formation on earth. Though, the craters are eventually filled in by sediments in most cases.
The orbit or the path that asteroids follow sometimes coincides with the orbit of the earth. An orbit is a path along which any object revolves around the sun. Due to coinciding of paths at certain points, the asteroids might collide with the Earth with a lot of force. Please note that the scientific formula of the force of impact is: mass into acceleration. This forceful collision of the asteroid with the Earth is known as Asteroid impact.
|What Is An Asteroid Impact And When Is The Next Asteroid Impact Expected?|
If we consider a scenario wherein a 10 km big object hits the Earth, it would carry an energy equivalent to 60000 megatons of TNT. Wherein, 1 Megaton equals 4.2 into 10 raise to power 15 Joules and is equivalent to the energy released when million tons of Dynamite get exploded.The impact caused by hitting of a 10 Km object can be said to be equivalent to the energy carried by a massive earthquake of 9.4 Richter scale. A classic example of Asteroid impact is the, Yucatan impact that occurred vaguely 65 Million years ago. The energy released from this asteroid impact caused a phenomenon of a Global Firestorm followed by a Cold snap and eventually Global warming that lead to perishing away of Dinosaurs. Such asteroid impacts have lead to extinction and perishing away of many species of plants and animals in the past.
In the past 10000 years, as many as 350 asteroid collisions have occurred with the Earth some leading to considerable damage.In the coming 10,00 years such impact, if occurs might lead to mass destruction of population, cause famines and forest fires which can have some serious adverse effects on life in general be it flora or fauna.
When is the next Asteroid impact expected?
The chances of next asteroid impact are seen to be emerging in the year 2017 during the month of September. Though, the odds of it hitting the Earth are remote, say something like 1 in 250 Million.It is not possible to give an exact picture regarding it’s orbit since, there are multiple possible trajectories that this Asteroid could follow.
The asteroid that is likely to cross the path of Earth in 2017 is 2013 TX68 and it is around 110 feet in diameter. If this Asteroid were to enter the strata of our Atmosphere, it shall produce an air burst and release an energy equivalent to two times the amount that was release when a 65 Feet wide asteroid entered the atmosphere near the Chelybinsk region of Russia.
