This was inspired by the Shoemaker-Levy comet. When the comet was discovered in 1993, it had already brushed Jupiter and was broken into pieces that were caught in the planet's gravity. In July, 1994, the pieces of the comet crashed into Jupiter, providing some impressive images. It was a rare and spectacular event that got a lot of attention from anyone interested in astronomy.

"In the song, the comet is used as a metaphor for an encounter with a woman. She shows up suddenly, leaves an impact, then disappears." but Im not sure if that is only a rumor.
