Ukrainian astronomers discover an asteroid, called 2013 TV135, with the power of 2,500 nuclear bombs. It's officially described as "potentially hazardous." You've been warned.

I know from all the financial ads on TV that you like to plan your portfolio well in advance.

Might I therefore suggest that you keep a vast stack of money for the vacation of several lifetimes in the early summer of 2032?

You see, I don't want to alarm you excessively, but the world might end in August 2032.

Yes, the chances are small -- perhaps 1 in 63,000. But, as they say in lottery ads, you never know.

My mildly alarmist tone comes from hearing that scientists at the Crimean Astrophysical Observatory in the Ukraine have spotted a rather large asteroid.

As Russia's RIA Novosti observed it, this menacing object is more than 1,300 feet wide and packs within it the power of 2,500 megatons of TNT. It is, indeed, the sumo wrestler of asteroids. And it's headed our way.

It's already got a name: 2013 TV 135. This seems a little disappointing. Why can't we name asteroids like hurricanes? Why can't this be Asteroid Annie? Why not Asteroid Spumante? Or, at the very least, The Big One?
