A relatively large asteroid, discovered last August 28, will pass over the Earth-Moon on 14 September 2012 to "only" 2.8 million kilometers (equal to 7.4 lunar distances) away, as described in this Previous article. A relatively small distance in relation to the large astronomical distances. Actually another space rock, 1.1 kilometers in diameter, called QC8 2012 and coming from the vicinity of Jupiter will transit at about 8.7 million kilometers from our planet (22.7 lunar distances). For both bodies, who will present a magnitude (brightness) 14-15, there is no danger of impact with the Earth. They will be a good target for the average amateur instruments.
