bolide

The word bolide comes from the Greek βολίς (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". The bolide term is generally used for fireballs reaching magnitude -14 or brighter. Astronomers tend to use the term to mean an exceptionally bright fireball, particularly one that explodes (sometimes called a detonating fireball).
