[Mike Darancette]

there's a strong possibility that the debris trail (a cone shape) would affect us.

But she shows the debris field leading the comet. The Comet's tail is not the debris field.

[Yosemitest]

"The Comet's tail is not the debris field."

After the comet departs the Sun and its "Tail" precedes it,
then WHAT is the preceding "Tail" made of,

if not made of blown "dust and debris" ?
