A falling star, also called "meteor" is a rock that orbitates the Earth. Her dimensions could variate (range from 1 m or less tovarious kms). When the meteor enters the atmosphere, it begins to fall, attracted by the gravity, and the contact with the air at great speed (till tens of kms/s) makes it to burst. In few seconds it will disappear, totally consumed by the heat. Meteors are formed by the disaggregation of a comet or planet. In some periods of the year the Earth's orbit around the Sun passes through the pathway of ancient destroyed comets (so it encounters lots of meteors, as it happens with Perseids meteors in August).

A falling star is a meteor (or meteorite if it hits the ground). The majority of them are small (grain of sand to pea sized) and are either stoney material or pieces of nickel iron.
99% burn up in the upper atmosphere due to air friction as their speed is very high( miles per second).

What they called in certain litterature as a moving star which disapears is really a meteor.
It is invisble till it enters the earth's atmosphere and due to friction it starts burning giving off a streak of light in the sky.
Then disapears as it hit the ground.

A shooting star or a falling star is the common name for the visible path of a meteoroid as it enters the atmosphere..
