Fascinating, I didn’t know that comets had magnetic fields, let alone a field that’s stronger than a Mars’ field. It makes sense in retrospect because some diffuse material flying off the comet is going to be ionized by the Sun’s light and flowing ions make magnetic fields.

  7. Something drastic had to of happened to Mars early on in the forming of our solar system! Or it was just unlucky enough not to have enough iron or metals that formed it. Maybe this is the way most planets are formed in Star systems the first three or four had the most heavy metals in them who knows but it sounds and seems like that could be true.
