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]
Meteoritics [note 1] is the science that deals with meteors, meteorites, and meteoroids. [ note 2 ] [ 2 ] [ 3 ] It is closely connected to cosmochemistry , mineralogy and geochemistry . A specialist who studies meteoritics is known as a meteoriticist .
Electrophonic bolide – a meteoroid which produces a measurable discharge of electromagnetic energy during its passage through the atmosphere. Enstatite achondrite – a meteorite that is mostly composed of enstatite. Usually part of the aubrite group. Enstatite chondrite – a rare form of meteorite thought to comprise only 2% of chondrites.
The Orionids meteor shower, often shortened to the Orionids, is one of two meteor showers associated with Halley's Comet. The Orionids are so-called because the point they appear to come from, called the radiant , lies in the constellation Orion , but they can be seen over a large area of the sky.
A meteor air burst is a type of air burst in which a meteoroid explodes after entering a planetary body's atmosphere. This fate leads them to be called fireballs or bolides, with the brightest air bursts known as superbolides. Such meteoroids were originally asteroids and comets of a few to several tens of meters in diameter.
