Why do meteoroids fall into Earth?
The rocky debris, consisting of mostly sand-size particles, continues in an elongated orbit around the Sun close to that of its parent comet. When the earth intersects this orbit in its annual trip, it can run into this debris, which burns up on entry into the earth’s atmosphere, producing a visible shower of meteors.
