Por lo visto el asteroide exploto en la atmosfera y no llego a impactar contra el suelo ....
Last week when asteroid 2008 TC3 entered Earth's atmosphere over Sudan, "classified assets" were watching. Without naming names, the US government has released a summary of what they saw: "Sensors aboard US satellites detected the impact of a bolide over Africa on 7 October 2008 at 02:45:40 UT. Initial observations put the object at 65.4 km altitude at 20.9o N, 31.4o E. The object detonated at an altitude of approximately 37 km at 20.8 o N, 32.2o E. The total radiated energy was approximately 4.0X1011 joules, equivalent to ~0.1 kilotons of TNT."
