What Are The Chances That Another Comet Will Collide With Earth?

Updated on August 31, 2011

By Christine B.

The chances are pretty darn high, actually. And there’s not much we could do about it when it happens.

A comet scientists have named, Elenin, is heading for Earth
and is due to arrive in November 2011. When it was first
discovered in December 2010 its trajectory was calculated
to pass about 9 AUs from Earth. (An AU is the distance from
the Sun to the Earth.) However, new calculations indicate
that it just might come a lot closer than originally thought. The closer the comet comes to Earth the easier it will be for astronomers to calculate its exact
trajectory. Even if the main comet doesn’t hit Earth, it has a
large debris field traveling with it, and some of those objects
might hit Earth and cause considerable damage.

Whether this comet will collide with Earth or not, there are lots more out there that eventually might. It has happened before, and it is highly likely that it will happen again at some point in time. This is one reason why continued funds and efforts should be funneled into projects that could offer the human race alternative living environments, should our world come to an untimely end. Those who say that the space program is a waste of money are not taking into consideration some of the most important reasons behind NASA’s efforts to find life or the possibility for our survival on other planets. Aside from the numerous advanced technology items NASA has given us for our everyday lives, (microwaves, protective clothing for our fireman, etc.) its search for other habitats for the human race is of the utmost importance.


. . . that on June 30, 1908 a blazing fireball hit the Earth at Tunguska, Siberia and devastated an area about half the size of Rhode Island? Fires burned for weeks afterward and the sound of thunder could be heard at great distances. It's been estimated that its explosive force was equal to more than 2,000 Hiroshima-type atomic bombs. No one has ever been able to unequivocally determine the cause of this devastation, as no meteorite debris has ever been
found in the area. Theories include a comet hit, a UFO with a great deal of atomic energy on board exploded in the area, and even a Tesla experiment gone bad. The true source of this incident remains a mystery.

      Earth colliding with a comet, regardless of the size of the comet, can have a catastrophic effects if it happens in a highly populated city.Thanks for this hub.
