>>1. Any natural extraterrestrial object that has touched the earth is
considered a METEORITE<<
So, if one of the moon rocks brought back to earth by the apollo astronauts
is dropped...you'd call it a meteorite? :O)
>>2. Any natural object in free space that is smaller than an asteroid is
considered a METEOROID<<
Pretty much so.
>>The contention seems to be during the fall to earth.
When during this atmospheric, ablative period, and post luminescent
/dark period is it proper to use the generic terminology and call it a
METEOR?<<
During this dark period, there will be no ablation...it's too slow for that.
and to say that a meteor is post luminescent doesn't make any sense either.
Since a meteor is the light phenomenon itself...not the object. During the
objects dark phase, there's no longer a meteor present.
