Meteoroid a Falling star

Post  pawansoni on Wed Oct 15, 2008 4:12 am

A meteoroid is a small sand- to boulder-sized particle of debris in the Solar system. The visible path of a meteoroid that enters Earth's (or another body's) atmosphere is a meteor, commonly called a "shooting star" or "falling star". On reaching the ground, a meteor is then called a meteorite. Many meteors are part of a meteor shower.

The average meteoroid enters the atmosphere at between 10 and 70 km/sec. But all but the very largest are quickly decelerated to a few hundred km/hour by atmospheric friction and hit the Earth's surface with very little fanfare. However meteoroids larger than a few hundred tons are slowed very little; only these large (and fortunately rare) ones make craters.

During some nights, shooting stars or meteors can appear at intervals from as high as a few minutes to as low as a few seconds. This phenomena is called a meteor shower, which occurs when the Earth comes across a stream of debris in the trail of a comet. When the debris, which are small enough to undergo disintegration, enter the atmosphere, they ignite – which we then observe as streaks of light.

A meteoroid is a sand- to boulder-sized particle of debris in the Solar System. The visible path of a meteoroid that enters Earth's (or another body's) atmosphere is called a meteor, or colloquially a shooting star or falling star. If a meteoroid reaches the ground and survives impact, then it is called a meteorite. Many meteors appearing seconds or minutes apart are called a meteor shower. The root word meteor comes from the Greek meteōros, meaning "high in the air".
