[Yosemitest]

How wide was the "V" pattern of Ison as it left the Sun?
What makes you think that

once those pieces of Ison came apart into that "V" pattern,
that they will suddenly change direction again, and follow the original course or parallel it?

I ask again,

"What is the impact energy of a piece traveling well over 300,000 miles per hour? "

Not wide enough to be a threat to earth.
Plus, space is a very large place.
Ison would have to violate physics to be a threat.
We are more threatened by November omega orionids than by the debris of ison.
