[QUOTE="Channel Hopper, post: 644331, member: 175144"] A comet would have to hit the ground/ocean at a final diameter of some 2 kilometres. At the fastest speed and minimal angle (ie perpendicular to the surface/head on) the original diameter would have to be some 7 to 10 kilometres in diameter. Very few comets have that sort of mass (the Oort belt has some rather large stuff sitting out there though), and even fewer are anywhere near the orbit of this planet. The average collision rate of planetary / climate damaging comets is approximately 1 in every 50 million years. Real global killers are about six times less common. [/QUOTE]
