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?

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.


Old enough to know better(but)still young enough not to care
