that are to pass closely between earth and mars 37655 IIIapa, 2003gy,and 2003mu
the sit offered as well as this site
http://neat.jpl.nasa.gov/ at least I cannot find info, but

http://www.spaceweather.com/ displays 2003gy between
earth and venus and the other two between earth and mars.

I dont believe it was that they were headed to earth, it was more
like the three or two would be close and in between to be pulled
or collide with each other and or one of the planets.

As others have posted we can only remain calm,seems this cannot
be proven or disproven so time will tell.
WolkC how about a skittles rainbow shower?
