From Dragon Ball Wiki, the ''Dragon Ball'' encyclopedia
Comet Camori was the comet that Paragus attempted to use to destroy New Planet Vegeta. It eventually crashed into the planet, destroying it. Paragus was crushed in his Attack Ball and thrown into the comet. Nobody was killed by it (except for the scientist and the soldiers working for Paragus, though it is unknown if they themselves were killed by the comet or Broly's earlier attack) since the Z Warriors evacuated everyone into a spaceship. Broly also managed to escape the planet unnoticed by the Z Warriors, however, they did find out seven years later.
