For Dan Apted . . .
Dan Apted’s reply to Marcia from here.
It could be that the old theories on comets is correct. But I need to see some evidence of solar wind acting on a known object.
How about the ACE spacecraft at Lagrange 1?
Using wind-data from NASA’sACE spacecraft, this web page displays dynamic modeling of the Earth's bow shock and magnetopause -- with details.
As for accelerating the dust from the comet, that's what outgassing does. The debris is launched in all direction, leaving a trail of dust behind.
There’s more out there, and just a Yahoo or Google away,
