Meteor shower
From Memory Alpha, the free Star Trek reference.
A meteor shower (also called a meteor swarm or meteor storm) is an astronomical phenomenon caused by meteors, that poses a hazard to starships.
In 2269, the USS Enterprise discovered Winston's trading vessel adrift in the Romulan Neutral Zone; an apparent victim of a meteor swarm. (TAS: "The Survivor")
In 2270, Spock noted that the historical records of the Dramian system were "spotty, at best, going back 19 years," reporting that "mostly, they're technical data, meteor showers, auroras, [and] radiation reports." (TAS: "Albatross")
After the USS Excelsior was hit by a subspace shockwave created by the destruction of the Klingon moon Praxis in 2293, Captain Hikaru Sulu's first comment after the ship was safely clear of the shockwave was "that was no meteor shower." (Star Trek VI: The Undiscovered Country; VOY: "Flashback")
In 2370, Cardassian Professor Natima Lang claimed that her Cardassian shuttle was caught and damaged in a meteor storm. It was later revealed that the damage caused to her ship had actually came as a result of Cardassian disruptor fire. (DS9: "Profit and Loss")
