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.
An Earth-grazing fireball (or Earth grazer) [2] is a fireball, a very bright meteor that enters Earth’s atmosphere and leaves again. Some fragments may impact Earth as meteorites, if the meteor starts to break up or explodes in mid-air. These phenomena are then called Earth-grazing meteor processions and bolides. [1]
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.

If meteoroids survive their trip to Earth without burning up in the atmosphere, they are called meteorites, NASA says. Unlike most meteor showers, the Geminid meteor shower doesn't originate from ...
A meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky. These meteors are caused by streams of cosmic debris called meteoroids entering Earth's atmosphere at extremely high speeds on parallel trajectories. Most meteors are smaller than a grain of sand, so almost ...
The meteors are fast and bright, with a yellow or greenish hue due to their chemical composition. “They’re pretty meteors!” Bill Cooke, lead for the Meteoroid Environment Office at NASA’s ...
Maximum meteor activity is expected to peak between 10 a.m. ET to 1 p.m. ET (15 to 18 Coordinated Universal Time) on January 3, which favors Alaska, Hawaii and far eastern Asia, said Bob Lunsford ...
