Meteor _ Fireball Falls in Mexico

Meteor shower, temporary rise in the rate of meteor sightings, caused by the entry into Earth’s atmosphere of a number of meteoroids (see meteor and meteoroid) at approximately the same place in the sky and the same time of year, traveling in parallel paths and apparently having a common origin. Most meteor showers are known or believed to be associated with active or defunct comets; they represent Earth’s passage through the orbits of these comets and its collision with the streams of debris (typically of sand-grain to pebble size) that have been left behind. The showers return annually, but, because the densities of meteoroids in the streams (commonly called meteor streams) are not uniform, the intensities of the showers can vary considerably from year to year.
