Comets on fire - comets on fire - How to Make Gold Glitter Firework Comets - Skylighter


Such relatively small rocks falling from space usually cause little damage or injury. However, the danger increases considerably when these cosmic missiles are only marginally larger. An object the size of a large house could easily wipe out a good-sized city. And the impact of an asteroid or comet a little more than half a mile across would release about 1 million megatons of energy (several million times more than the energy released by the atomic bomb dropped on Hiroshima, Japan, in 1945). This would be enough to create a global catastrophe that would kill hundreds of millions of people and animals.
