Re: Asteroid dust may influence weather, study finds
___From the article: "But the size of an asteroid entering Earth’s atmosphere is significantly reduced by the fireball caused by the friction of its passage."
___It never ceases to amaze me how even the "experts" get this wrong. Friction has NOTHING to do with the heating of an asteroid on entry into the atmosphere. The heating is derrived from the air which is compressed in front of the entering object.
