The earths orbit passes twice a year throught a ring of debris that orbits the sun in an eleptical path. These bits of junk that the earth strikes during its transit of the ring are what ''fall'' as meteors.

Because of charted orbits. Most heavenly bodies have an orbit that can be tracked. The meteor events we are familiar with are the 'tails' of orbiting comets that pass near us at the same time every year shedding material that enters our atmosphere.
The Leonid shower begins in less than a week. It is from the P55 Temple/Tuttle Comet that has a 33 year cycle. Its closest pass by earth was last in 1998.

It's because the Earth is passing through the remnants of a comet. The Perseid meteors are an example of this. Since the Earth goes around the sun at a specific interval, we pass through the tailings at the same time each year.

Like the Leonid's & the Perseids?
Because As the earth oabits the sun in traveles through debris streams than are found in certain parts of the orbit.

everything revolves around our 'black hole' then closer things revolve around our sun, so do comets, which meteor showers come from, the dust or trail of the comets are the meteor showers, that are too orbiting
