300-meter asteroid will bypass close to Earth next week.

According to introduction data, the order of 200 to 500 meters in diameter is approaching 0.0193 astronomical units away. Asteroid (2012 QG42) would be "potentially dangerous because of their size" and "proximity"

According to press next week 'Earth is threatened by the approach of an asteroid more than 500 meters in diameter, "according to Italian astronomers have reported.

However the review information at JPL (Jet Propulsion Laboratory) spacecraft has noticed that the piece of rock called 2012 QG42 measures about 300 meters.

The minimum distance between the asteroid and the Earth would be reached from 13 to 14 September, at 05:12 UTC (02:12 hours Chile / Argentina), announced Remanzacco Observatory.

According to preliminary data, "the object of 200-500 meters in diameter" is approaching at a distance 0.0193 astronomical units (7.4 average distances from the Earth to the Moon). Thus, the asteroid 2012 QG42 would be "potentially dangerous because of their size" and "proximity", as astronomers Remanzacco.

During 2012 we have had close encounters with these objects, some of them here:

June 14, 2012 (the size of a residential area)

May 2012 (10 meters)

May 2012 (26 meters)

NASA estimates that there are 4,700 asteroids 'represent a threat to Earth'
