	A small mystery: this morning I had read on www.msnbc.com an article about a big asteroid which should pass at 13 times the Earth-Moon distance on Sunday.I had thought of linking the article here but first I went to www.nasa.jpl.gov seeking confirmation. There was not a line about it. I went back to www.msnbc.com and the article had disappeared.Someone had invented it? Tullio ____________

	One of the problems that the astronomers that are seeking these planet killers have is that these asteroids only reflect <4% of the light that hits them so they are in effect blacker than coal which if I remember reflect >10% of the light that hits it.As for puting a propulsion system on one some of these not only rotate they also tumble. ____________ To get back my youth I would do any thing in the world EXCEPT take Exercize,GET up early or be RESPECTABLE.
