A large-sized asteroid came close to the orbit of planet earth last month. It is called the asteroid 2013 TV135. It will be returning in 2032. Till then the danger has been delayed. Yet due to the fact that it is about the size of the earth itself, it is a hazard to spaceship earth’s future. Asteroids have rarely hit the earth’s surface in bygone times. But they are proof that one day by sheer chance one may strike our big blue planet.
On September 16th, 2013 asteroid came close. But that was still 17 times as far away as earth’s satellite, the moon. However, scientists estimate that chances of this asteroid colliding with the earth in 2032 are one in 63,000.
Therefore, the doomsayers’ prognostications can be taken with a grain of salt. We have 99.998% of the luck on our side as earthlings. But who can say of the remaining 0.002% which can be called the risky law of chance. The asteroid known as Apophis too had a one in 40 chance of a one-on-one collision with the earth in 2029.
However, later on scientists found that the probability ratio was close to zero. There have been rumors among the Russians whether we could nuke the asteroid out of existence before it collided with Gaia. Maybe the goal should be to discover the time frame in which the space object is to get close to earth and be prepared if it gets too close for comfort.
