I understand the EU has a different concept of what makes a meteor (not the iced dust ball)
Are you perhaps mixing up a meteor with a comet ?
I've just been looking at what establishment sciences defines as these two...from what I can gather , reading between the the lines ,there is no real difference , no sharp dividing line.
There is space debris ..... some has not spent too much time close to the sun ,and so has a higher component of volatiles .. this is labeled 'comet' when it does approach the sun ...the other has been sunning itself longer , so most of the volatiles have been boiled off by the heat from the sun ...labeled 'meteoroid' ...but no sharp division, a continuous spectrum of objects with different % of volatiles ...
Exactly the same as planets , the further out the planets are the more liquids and gasses they have, if you brought jupiter close to the sun , all the volatiles would go, and something like mercury would be left.
This UFO site is quite sensible ...http://cognizantnationhq.weebly.com/blo ... ase-proven
...and raises some good points.
