On Feb. 15, comet DA14 will come within 21,000 miles of earth. In cosmic terms; close enough to hear it whiz by. While not particularly large, at 150 odd feet, it could do considerable damage. Remember – a beach ball sized meteor could make a crater almost 20 feet deep and over 60 feet wide. There is no chance DA14 will collide with earth, at least not this time around.
Countless close calls populate our fragile existence. On April 13, 2029 Comet Apophis, at well over 500 feet; will come within a projected 19,400 miles of earth. This one is large enough to obliterate a major city In November of this year comet ISON; not close at 2 million miles, yet shining many times brighter than the full moon; will dazzle the naked eye.
I wish more of us pondered the cosmos. Governed by nothing but science; physics is the universal God. The United Nations itself, mandates that celestial bodies are for the benefit of all mankind Unfettered by politics, God, or back room handshakes; the universe is free to operate purely on science. No doubt the concept is lost on fundamentalists; the irony being that it could quite possibly be a space rock that bites us in the ass one day.
As we squabble like grade schoolers on the playground, squander our resources, and throw tantrums over religious righteousness – a big ass space rock strikes me as poetic justice. Not a punishment from God; simply a cosmic spanking, unleashed when orbits eventually collide.
