AT: "xx" Component 37329 was the temporal designation for a rogue comet discovered by the USS Voyager during their journey in the Delta Quadrant.
In an alternate timeline, Chakotay discovered on Annorax's Krenim weapon ship in 2374 that eight months earlier, component 37329 caused Voyager to set a course so the ship would avoid it completely, which led to them entering Krenim space. Chakotay suggested that Annorax remove the comet from the timeline, so Voyager would not encounter the Krenim Imperium and be severely damaged by their ships. However, upon running a simulation, it was discovered that removing component 37329 from time would result in the destruction of 8,000 species, as pieces of the comet impacted on a planet centuries before and led to life being created.
