[meteorite-list] Near Misses

[Peter A Shugar]

Hello list,
Stated in it's smplest terms, the near miss will preturb the oribital 
parametersof the smaller body way
more than the much larger earth. Yes !!!!!
However----- 
The only way that the object will come back to haunt our placid life here on 
earth is IF the orbital parameter
 dealing in TIME is precisely the same time, (or some whole number 
multiple), or a fraction of the earth's orbit.
Then and only then will we need to worry. I rather doubt the orbits of any 
near miss objects have this particular
orbital parameter.
One last thought, I do not have the computer facilites to research this, but 
a near miss by an object with an oddball
timed orbit MAY have the errors add up so that it COULD come back to haunt 
us, but I doubt we will be around
to worry about it.
So--------
Pete
