Too mnay objects running around. 1 AU = 149,600,000 km
Comet Holmes = 1.6345 AU from earth this evening (in two days it will be down to 1.630 AU, better duck) This gives a distance of 244,500,000 km Speed of light is 299,800 km/sec So Light Distance = 816 seconds (give or take) Larry On Wed, October 24, 2007 9:29 pm, Sterling K.
