if a meteoroid hits earth's surface it is called
Meteoroid When a meteoroid, comet, or asteroid enters Earth's atmosphere at a speed typically in excess of 20 km/s (72,000 km/h; 45,000 mph), aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a meteor or "shooting star". A series of many meteors appearing seconds or minutes apart and appearing to originate from the same fixed point in the sky is called a meteor shower. If that object withstands ablation from its passage through the atmosphere as a meteor and impacts with the ground, it is then called a meteorite.
Armageddon (1998 film) A massive meteor shower destroys the orbiting Space Shuttle Atlantis and bombards a swath of land around the North Atlantic. NASA discovers through the Hubble Space Telescope that the meteors were debris propelled from the asteroid belt by a rogue asteroid roughly the size of Texas, christened "Dottie" by its discoverer. The asteroid will collide with Earth in 18 days, causing a second extinction event. NASA scientists, led by Dan Truman, plan to trigger a thermonuclear detonation at least 800 ft (244 m) inside the asteroid to split it in two, driving the pieces apart so both will fly past the Earth. NASA contacts Harry Stamper, considered the best deep-sea oil driller in the world, for assistance. Harry insists he will need his full team to help execute NASA's plan, and they agree to help but only after their list of unusual rewards are met.
