That would have been a Fireball (also known as a Bolide) which is a very bright meteor. You're very lucky to have witnessed one.

The word bolide comes from the Greek βολίς (bolis) [14] 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.[15] 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.

Asteroids and comets don't whizz throught the atmosphere, they orbit the sun. On the rare occasion one enters the atmoshere it causes massive damage. This happened in Tunguska in 1908 which is believed to have been caused by an impacting comet, although some scientists think it was an asteroid. There was a theory that it was a black hole passing through the Earth, but not many (if any) scientists believe that now.

Astoid/ Comet... what is the difference


Simply put, a comet is a ball of ice (mostly) and an asteroid is a lump of rock.
