[edit] Bolide
The word bolide comes from the Greek βοÎ"ις, (bolis) which can mean a missile or to flash. The IAU has no official definition of bolide and generally considers the term synonymous with fireball.
Bolide
Large, brilliant meteors that enter the Earth's atmosphere. Friction between a fast-moving meteor and Earth's air molecules generates tremendous heat, which causes the meteor to heat up, glow, and perhaps disintegrate.

- but now specially restricted to those luminous bodies known as shooting stars, falling stars, fireballs and bolides.
Impact events are caused by the collision of large meteoroids, asteroids or comets (generically: bolides) with Earth and may sometimes be followed by mass extinctions of life.
Brilliant meteors, known as fireballs, occur singly and generally consist of a luminous head, followed by a cometlike train of light that may persist for several minutes; some, called bolides, have been seen to explode with a sound like thunder.

Tens of thousands of fireballs fall to Earth every year (only about 5,000 of these become bolides), but very few of these are actually observed. This is due to many reasons: ...
The third effect is that of radiation pressure which will push less massive particles into orbits further from the sun - while more massive objects (responsible for bolides or fireballs) will tend to be affected less by radiation pressure.

Definition: meteor: (also "shooting star" or "falling star") a bright streak of light in the sky caused by the entry into Earth's atmosphere of a meteoroid or a small icy particle. Very large, bright ones are called fireballs and bolides.
bolide An exploding meteorite. bow shock The outermost part of a planetary magnetosphere; the place where the supersonic flow of the solar wind is slowed to subsonic speed by the planetary magnetic field.
or even interpreted as attacks by heavenly beings against terrestrial inhabitants. Some authorities interpret references to "falling stars" in Gilgamesh, the Book of Revelation and the Book of Enoch as references to comets, or possibly bolides.
Sporadic meteors may be seen at a rate of about five to ten per hour from an average site. Meteor showers occur when the Earth passes through debris left by a disintegrating comet. Very large meteors are called fireballs or bolides if they explode.
Estimates of their mass suggest that their density is too low for gravitational collapse. They tend to lie in regions of much dust but less gas than would be expected for star-forming regions. [H76]

kilometres across, large enough to strip away much of the northern hemisphere crust and give rise to Mars' hemispheric dichotomy. On the Moon, the 2,600 kilometre wide South Pole Aitken Basin was produced by the largest lunar-striking bolides.
Large meteoroids, which produce longer meteors reaching a magnitude of -10, are called fireballs. Tens of thousands of them fall to Earth each year, around five thousand of which break up and explode. Such explosive meteors are called bolides.
