The definition of a meteor is a small body of matter from outer space that comes into the atmosphere of the Earth and that looks like a streak of light due to iridescence caused by friction.
A shooting star caused by a small object from outer space entering the earth's atmosphere is an example of a meteor.
A meteor in the sky.
meteor definition by Webster's New World
the luminous phenomenon observed when a meteoroid is heated by its entry into the earth's atmosphere; shooting star; falling star
loosely a meteoroid or meteorite
Meteorol. any atmospheric phenomenon, as precipitation, lightning, or a rainbow
Origin: Middle English ; from Midieval Latin meteorum ; from Classical Greek meteōron, plural meteōra, things in the air ; from meteōros, lifted up, in air ; from meta, beyond (see meta-) plush eōra, a hovering in the air (akin to aeirein, to lift up)
A bright trail or streak that appears in the sky when a meteoroid is heated to incandescence by friction with the earth's atmosphere. Also called falling star, meteor burst, shooting star.
Origin: Middle English metheour, atmospheric phenomenon, from Old French meteore, from Medieval Latin meteōrum, from Greek meteōron, astronomical phenomenon, from neuter of meteōros, high in the air : meta-, meta- + -āoros, lifted; akin to āeirein, to lift up; see wer-1 in Indo-European roots.
A bright trail or streak of light that appears in the night sky when a meteoroid enters the Earth's atmosphere. The friction with the air causes the rock to glow with heat. Also called shooting star.
A rocky body that produces such light. Most meteors burn up before reaching the Earth's surface. See Note at solar system.
Usage The streaks of light we sometimes see in the night sky and call meteors were not identified as interplanetary rocks until the 19th century. Before then, the streaks of light were considered only one of a variety of atmospheric phenomena, all of which bore the name meteor. Rain was an aqueous meteor, winds and storms were airy meteors, and streaks of light in the sky were fiery meteors. This general use of meteor survives in our word meteorology, the study of the weather and atmospheric phenomena. Nowadays, astronomers use any of three words for rocks from interplanetary space, depending on their stage of descent to the Earth. A meteoroid is a rock in space that has the potential to collide with the Earth's atmosphere. Meteoroids range in size from a speck of dust to a chunk about 100 meters in diameter, though most are smaller than a pebble. When a meteoroid enters the atmosphere, it becomes a meteor. The light that it gives off when heated by friction with the atmosphere is also called a meteor. If the rock is not obliterated by the friction and lands on the ground, it is called a meteorite. For this term, scientists borrowed the -ite suffix used in the names of minerals like malachite and pyrite.
