Sample text

Many meteoroids enter the atmosphere at considerably higher speeds than these and survive. Meteoroids encounter enormous forces from the pressure of the air resisting their motion. Frequently, the force on a stony meteoroid, especially on the forward end, is sufficient to cause the mass to break into several smaller pieces. These pieces have a better chance of survival than the larger single mass, since smaller stones with 49 Mass retained (%) The initial velocity of a meteoroid determines how much material will be ablated during its atmospheric passage.

The meteorite had penetrated 10 feet into the soft earth, and a farmer nearly drove his tractor into the hole. For twenty-eight years this meteorite from the nowfamous Norton County, Kansas, fall remained the largest single stony meteorite ever recovered, and the largest meteorite recovered from a witnessed fall. (On March 8, 1976, explosions and a fireball preceded the fall of 4 tons of stony meteorites near Jilin, China. 7 tons. ) in the Beginning-Superstition and Myth Hundreds of people witnessed the fall of the Norton County, Kansas, meteorite.

The light from the fireball is usually seen over a wide area, often hundreds of miles from the spot where it comes to rest on the ground. Though it is possible for the sound accompanying the fireball to be heard over as wide an area, it usually is heard only by people close to the impact point, within 25 or 30 miles. The height at which a burning meteoroid first becomes visible as a fireball depends on its initial mass and velocity when it enters the uppermost part of the atmosphere. All meteoroids in space are moving at cosmic velocities.
