I still have differences of opinion with your theory that
"They don't however "swirl along" picking up objects and debris as they go. "
The Leonids were generated from the
Comet 55P/Tempel–Tuttlewhich
is estimated to have a nucleus of mass 1.2×1013 kg[5] and radius 1.8 km[5] and a stream of mass 5×1012 kg.[5]
Comet Tempel–Tuttle is expected to return on May 20, 2031 form it's
orbital period of 33 years and was last seen
Feb. 28, 1998.
QUESTION:
How different is Comet Ison from Comet Temple-Tuttle
in size ?
Here's what
I've found on Comet Ison.
April update: Early indications from students who have been processing data from NASA’s Swift satellite, estimate the comet to be around 3 miles in diameter.
They have reached this conclusion by observing the amount of ice and dust emitted from ISON’s surface as it falls through space toward the Sun.
Now if I read things correctly, Comet Ison is larger than Comet Tempel–Tuttle.
Doesn't anything with mass have its own gravity, and therefore can "tug at" other bodies that have mass ?
If Comet Tempel–Tuttle left the Leonids in its trail, why can't Comet Ison do similarly ?
Where is your logic
that allows one comet to do that,
but not another LARGER comet ?
I still have differences of opinion with your theory . . . Well you go right ahead, except that it's not a theory. Comets and their motion through the solar system are EXTREMELY well understood. I'm just restating facts that have been proven and observed many thousands of times.
As for the gravity, yes all mass has gravity and pulls on everything else in the universe. But the forces involved are related to the masses of the objects divided by the inverse square of the distance between them. The comet does have a gravitational attraction but it is quite small and the farther you get from it the smaller the force becomes -- very quickly. Anything that could be swept up by a comet would have to be extremely close to it, and as has already been pointed out, the objects and particles in the asteroid belt are extremely far apart. The forces just aren't there to be "sweeping up" things other than the occasional dust particle that it impacts, let alone objects large enough to cause any effect on Earth -- assuming it were to pass close to Earth ---- WHICH IT WON'T.
