7 lakh asteroids detected: Asteroids, if hit Earth, can cause massive destruction on the planet and many of you would agree with it. Right? It is predicted that there are thousands of asteroids orbiting the space. Well. You may not be knowing the exact number of asteroids orbiting the space. Do you?
According to a report published by spacetelescope.org, there are more than 700 000 asteroids that have been found in space. The report said, “More than 700 000 asteroids have been identified to date, and predictions indicate that many more might be out there, each left over from the early days when planets were taking shape around the Sun.”
“Asteroids are mainly found in an area called the ‘main belt’, between the orbits of Mars and Jupiter,” it added.
In recent days, we saw many asteroids including 2019 NN3, 2019 MB4, 2019 MT2, 2006 QV89, 2016 NO56M, RF12 and others going past through our planet. We were fortunate as these deadly asteroids did not collide with the Earth.
It is to be noted that the asteroids can approach towards the Earth due to the gravitational forces that affect them. Therefore, our fortune can be turned into misfortune anytime.
In that case, what should we do? Should we destroy those asteroids? Well, the various space agencies including NASA can develop such technologies that can destroy asteroids which pose danger to our planet. But, it won’t.
Every year on 30 June, the global “Asteroid Day” event takes place to raise awareness about asteroids and what can be done to protect Earth from possible impact. The day falls on the anniversary of the Tunguska event that took place on 30 June 1908, the most harmful known asteroid related event in recent history.
In related news, on December 18 last year, a large meteoroid was exploded over the Bering Sea, however, it went unnoticed due to the remote location. According to the NASA, the explosion of meteoroid unleashed around 173 kilotons of energy, more than 10 times that of the atomic bomb blast over Hiroshima in World War II. Also, it was the most powerful explosion in the atmosphere since the fireball that burst over the Russian town of Chelyabinsk in 2013. That was 440 kilotons and left 1,500 people injured, mostly from glass flying out of smashed windows.
