Cassie (OP) User ID: 2514 United States 11/11/2005 07:07 PM Report Abusive Post Report Copyright Violation | Die Bunker, Interesting! From the first link you gave: Each day as many as 4 billion meteoroids, most miniscule in size, enter earth´s atmosphere. Most of these meteors burn up from atmospheric friction and never reach the ground. Only a few larger and more dense meteors reach the earth´s surface and make an impact. 4 Billion a day? Good Gravy! No wonder Informer (I think it was) always said... WATCH THE SKIES...SOON! |

Anonymous Coward User ID: 38523 United States 11/11/2005 08:22 PM Report Abusive Post Report Copyright Violation | This oneīs orbit runs close to the elliptic, just inside Venusīs orbit to just outside Earthīs orbit. Thereīs another close approach to the Earth in Jul 2013, and another in jul 2022. It also has three close calls with Venus before 2022. Wouldnīt all these close calls effect itīs orbit??? |
