Why is the meteor visible only once but comet may be visible at regular intervals?

difference between comets and meteors

a meteor is a rock or piece of space debris that enters the earths atmosphere and usually burns up before reaching the ground. also known as a shooting star. a comet is usually larger and i think composed of rocks and ice. comets follow an orbit created by the gravity of the sun mostly and maybe affected by the planets on a smaller scale. different comets pass within the view of the earths inhabitants at various intervals based on their orbit or elliptical path. like haleys comet...every 76 years it swings by earth, leaves, and travels on a similar oval or roundish path through the solar system and eventually passes us again. i think its 76 years anyway. hope i helped............Lisa
