That was my initial thought, but I am not so sure. Yes, the earth's magnetosphere would not be put into such a chaotic state, I agree, as it is much stronger and would be able to withstand the influence of the comet.D_Archer wrote:With Earth the repulsion would be greater (due to strong mag field) which would in turn result in less "chaos" because the asteroid could not affect our atmosphere in the same was as Mars's atmosphere was now.willendure wrote: The question that comes to my mind is, if it has been a planet with a stronger magnetic field, would the interaction have been a more or less violent one?
I am wondering if such an interaction would be a more energetic and violent event. The comet interacting with Mars' weak field, is like a lorry driving through a pile of dried leaves on the road and scattering them. The comet interacting with Earth's much stronger field might be like two lorries colliding. The two stronger magnetic fields would be squashed up against each other, containing much more energy - would that then be released as a big current flow, perhaps resulting in mega lightning, or at least some kind of super aurora effect?
