A meteor of the Leonid meteor shower; the photograph shows the meteor, afterglow, and wake as distinct components The visible light produced by a meteor may take on various hues, depending on the chemical composition of the meteoroid, and the speed of its movement through the atmosphere.
The Leonids are famous because their meteor showers, or storms, can be among the most spectacular. Because of the storm of 1833 and the developments in scientific thought of the time (see for example the identification of Halley's Comet), the Leonids have had a major effect on the scientific study of meteors, which had previously been thought to be atmospheric phenomena.
In total, this meteoroid stream is the largest in the inner Solar System. Since the stream is rather spread out in space, Earth takes several weeks to pass through it, causing an extended period of meteor activity, compared with the much smaller periods of activity in other showers.
Very intense or unusual meteor showers are known as meteor outbursts and meteor storms, which produce at least 1,000 meteors an hour, most notably from the Leonids. [1] The Meteor Data Centre lists over 900 suspected meteor showers of which about 100 are well established. [2] Several organizations point to viewing opportunities on the Internet. [3]
Once it settles on the larger body's surface, the meteor becomes a meteorite. Meteorites vary greatly in size. For geologists, a bolide is a meteorite large enough to create an impact crater. [2] Meteorites that are recovered after being observed as they transit the atmosphere and impact Earth are called meteorite falls.
The meteoroid is at the bright head of the trail, and the recombination glow of the ionised mesosphere is still visible for about 0.7 seconds in the tail.

A bolide: a very bright meteor of an apparent magnitude of −14 or brighter. Fireball over the Bering Sea viewed from space (18 December 2018) The following is a list of bolides and fireballs seen on Earth in recent times. These are small asteroids (known as meteoroids) that regularly impact the Earth.
Meteoric iron – a native metal found in meteorites and a mixture of different mineral phases. Compare telluric iron. Meteorite Observation and Recovery Program – a scientific program that was centered in Canada. Meteoriticist – a scientist working on meteorites, meteors, and meteoroids.
