2010 RF12 (Virtual Impactor)
On the morning of September, 6 2010 I read in the YAHOU Minor
Planet Mailing List MPML a
live talk about the actual
NEOs.
After testing the position of one of them, I could easily take some images of
the object 2010 RF12 from my site.

(September,8)
The asteroid is passing the Earth at
September, 8 21:12UT in around 79.000 km
distance. No impact will occur.
The body size is 6-14 meters in diameter. Here you find a
Calculator for possible crater sizes and energy sums.
