444-Near Comets

Although no comet nucleus impact on the Earth has been conclusively identified, there is some evidence that suggests the 1908 Tunguska event in Russia, which knocked down trees over a 770 square mile area, could have been caused by a fragment of Comet Encke. However there is no doubt that the Earth's collision with dust and small debris left trailing from comets produces some of the meteor showers we enjoy so much.
