The comet is made up of crystals of ice, earth, and carbonaceous matter … As it approaches the sun, under the influence of heat and radiation, it emits gas. The material from which it is made is sublimates (transition from solid state to gaseous state without passing through the liquid state, author’s note). This is what makes the well-known and famous tail that can reach millions of kilometers.

So the meteorites are the dust leaving this tail. When the Earth meets their orbits, they penetrate the upper atmosphere at speeds of up to ten kilometers per second, always at the same time each year. Under the effect of friction, they deform, leaving a glowing path for a few seconds. This is what creates the shooter star.
