On Friday, Feb. 15, 2013,(that is tomorrow) the Earth is going to get a very close call by an asteroid.

Astronomers have named itas 2012 DA14. This asteroid rock is 50 meters (160 feet) wide, and will pass by close to 27,000 kilometers(17,000 miles) from the Earth’s surface. This is closer than geosynchronous satellites, so this really is a close pass!

But, astronomers say that this asteroid poses no threat to us right now, nor in the foreseeable future. Friday’s miss is just that: a miss.

However, it must be mentioned that on June 30, 1908, an asteroid, 100 meters wide, hit the earth in Russia , near Tunguska, Siberia, and exploded. The explosion, called ‘the Tunguska event’ is the largest impact event on or near Earth in recorded history.

The Tunguska explosion knocked an estimated 80 million trees down over an area covering 2,150 square kilometres (830 sq mi). It is estimated that the shock wave from the blast probably measured 5.0 on the Richter scale. An explosion of this magnitude is capable of destroying a large metropolitan area.

Estimates of the energy of the blast put it at about 1,000 times more powerful than the atomic bomb dropped on Hiroshima, Japan.

The possibility of direct hit by such asteroids has given rise to discussion on asteroid deflection strategies.

Will the Earth get hit by an asteroid on Friday, Feb. 15, 2013?

This subject reminds me of Russian Author and scholar Immanuel Velikovsky (1895-1979) who has written a controversial book "Worlds in Collision" (1950). This book is about a comet like object which passed near earth in the celestial sphere that had supposed to have taken place in historical times, (15 century BCE) in which that object changed Earth's orbit and axis, causing innumerable catastrophes. The Author quotes the evidence from historical texts of many people around the globe, from classical literature, like epics of the northern races, sacred books of the peoples of the Orient and Occident, traditions and folklore of primitive peoples, and old astronomical inscriptions and charts, archaeological finds, and also geological and paleontological material.

I read this book and "Ages in Chaos" also of the same author when I was a student. Though interesting for a layman like me, "Worlds in Collision" had caused a lot of disturbance in the Astrophysics community and his theory was summarily rejected "as the cosmic chain of events proposed by Velikovsky contradicts the basic laws of physics".

Still I consider it as an interesting book and selections from Immanuel Velikovsky's "Worlds in Collision " are available in the following URL:

Dear Naina Sir,

So far so good. Time is nearing noon in Sing. Chennai.
But there is a sudden shower of rains here! :rain:

Meteorite falls in Russia's Chelyabinsk region; damage and casualties unclear

MOSCOW – Russian officials say a meteorite has fallen in the Chelyabinsk region some 1,500 kilometers (930 miles) east of Moscow.
A spokesman for the Russian Interior Ministry, Vadim Kolesnikov, said the Friday morning fall caused a blast that broke windows.
There were no immediate confirmed reports of injuries, but Russian news agencies cited unnamed sources as saying several people were injured at a school in a thinly populated part of the region, which is on the eastern edge of the Ural Mountains.

Here is the latest youtube video on this Russian news:

I just wonder if the proximity to the earth's gravitational field simply pulled the asteroid into the earth. While the scientists were right in predicting its track, their formula seems to need some correction for the gravitational pull of the earth! So, the asteroid did crash into earth after all?

OMG! Really scary to see the asteroid crashing. So many are driving vehicles on the roads!

BTW, what happened to the computerized calculations which are supposed to be precise? :noidea:

It may not be related to the present one 2012 DA14..as it has to take another 10 hrs to come nearer..

Dear Naina Sir,

It is like காக்கை உட்காரப் பனம் பழம் விழுந்த கதை! That was a meteorite and NOT the asteroid.

This asteroid is NOT supposed to hit the earth!

Please watch a short video of the meteoroid hitting earth - here

If a large asteroid is on a collision path with earth, if the area that is likely to take the hit is densely populated with huge assets, and if the damage likely to be caused is unacceptable:

These are the solutions:

1. a missile with a thermonuclear warhead can be launched to destroy it into smithereen. The resultant particles will be so small that most of them on entry into earth's atmosphere will burn out because of friction.

2. Some of the space debries can be manipulated to do the same thing as the thermonuclear warhead as explained in 1 above.

3. If the size of the asteroid is so huge that a thermo-nuclear blast would still leave a large chunk of it hurtling towards earth, we can take evasive action as the last resort. The earth can be made to rotate a bit faster or even manipiulated to move faster in its trajectory away from the collision path. Only we will have to reconcile with the other consequences of earth spinning faster and moving faster in its trajectory. The cost of this action would be prohibitive but when it comes to survival it wont matter and is doable theoratically.

Cheers.

Dear Naina Sir,

Yes, it is a Strange coincidence

While the odds of an unrelated meteor impacting on the same day as an asteroid fly-by is astronomically high, experts are confident that the two objects are not linked. The meteor appeared nearly 12 hours before the expected fly-by time of the asteroid 2012DA14. Also, 2012 DA14 was predicted to approach the southernhemisphere at a steep angle relative to the Earth's equatorial plane. Since Russia is in the northern hemisphere, that would make it extremely unlikely. If this meteoric impact had occurred in the southern hemisphere, then serious questions would have to be answered.
