What Is The Difference Of A Bolide And A Superbolide?

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 term generally applies to fireballs reaching magnitude −14 or brighter. Astronomers tend to use "bolide" to identify an exceptionally bright fireball, particularly one that explodes (sometimes called a detonating fireball). It may also be used to mean a fireball which creates audible sounds. If the magnitude of a bolide reaches −17 or brighter it is known as a superbolide.
