Anonymous Coward User ID: 27760252 United States 01/29/2013 01:05 PM Report Abusive Post Report Copyright Violation | On Feb. 15th an asteroid about half the size of a football field will fly past Earth closer than many man-made satellites. Since regular sky surveys began in the 1990s, astronomers have never seen an object so big come so close to our planet. Quoting: Wash [link to science.nasa.gov] The article says that it STRIKES the Earth every 1200 years or so. How can it strike and keep on going? |

"Yeomans estimates that an asteroid like 2012 DA14 flies past Earth, on average, every 40 years, yet actually strikes our planet only every 1200 years or so." Key words there. An asteroid LIKE 2012 DA14 strikes our planet every 1200 years or so, but one LIKE 2012 DA14 flies past us like 2012 DA14 is about to do every 40 years or so. |

Western US gets left out of the picture pretty much altogether. Last Edited by Astromut on 01/29/2013 06:46 PM |
