Meteor swarm (meteor stream).
Meteoroids and dust, which are the remains of a cometary nucleus destroyed after several successive returns to the Sun, form this swarm. It revolves around the Sun in an orbit that is the site of the comet’s death. It then gradually disperses throughout the orbit, covering a significant portion of it. Nevertheless, in that place of the orbit, where the nucleus of the comet was located, for a long time remains the process of thickening the swarm, which when it meets the Earth causes the phenomenon of meteor shower”.”
