Several meteors that appear to radiate from one point in the sky (although they are all parallel) at a particular date each year, due to the earth regularly passing through them at that position in its orbit.
When Earth encounters many meteoroids at once, we call it a meteor shower.
If it's time for a meteor shower, you won't need a telescope, binoculars, or a high mountain to have a "star gazing" party.
Comets like earth and other planets, also orbit the sun, not in a nearly circular orbit, but quite in a lop-sided orbit.
As a comet gets closer to the sun, some of its icy surfaces boil off, releasing lots of particles of dust and rock. This comet debris gets strewn out along the comet's path, especially in the inner solar system (where we live) as the sun's heat boils off more and more ice and debris. Then, several times each year as Earth makes its journey around the sun, its orbit crosses the orbit of a comet, which means Earth smacks into a bunch of comet debris.
