User ID: 10262276 United States 02/29/2012 07:52 AM Report Abusive Post Report Copyright Violation | Tunguska-Sized Asteroid Homing on Earth - Asteroid 2012 DA14 An asteroid of the same class as one that allegedly detonated over Tunguska River in 1908 will pass by Earth next year, flying closer than some man-made satellites, according to NASA. The asteroid, 2012 DA14, will miss the planet by 26,900 kilometers on February 15, 2013, which is closer than satellites in the geostationary orbit of 35,700 kilometers, according to data on NASA’s website published Sunday. The asteroid, first detected by the Spanish Observatorio Astronomico de La Sagra, is between 40 and 95 meters in diameter and belongs to Apollo group of near-Earth asteroids, many of which are potential collision hazards. FULL STORY: [link to en.rian.ru] That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. "...the blood of Jesus Christ his Son cleanseth us from all sin." I John 1:7 "For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord."

Quoting: Anonymous Coward 11484417 ..27,000 kilometers - is the distance, that may be in the range of errors of astronomical calculations, and this short distance is actually evidence of real probability of a collision... more in: [link to hainanwel.com] 27,000 kilometers, is not going to bother this planet...it's called a "flyby"....nothing to worry about |
