comets stories

 
In August of 1883, an astronomer in Mexico named José Bonilla spotted hundreds of fuzzy objects passing in front of the sun that nobody could explain.

There's no reason you should be familiar with comet C/2010 X1 "Elenin." It's a relatively small ball of ice that's scheduled to pass us at a distance of 21 million miles on October 16th. If you are familiar with Elenin, it's either because you're an obsessive sky watcher, or because you've been reading too many doomsday and conspiracy websites.
