Comets

Comets appear every few years

Comets have highly elliptical orbits around the Sun

Comets are visible when they are close to the Sun

A comet’s orbit is fastest near the Sun due to the Sun’s gravity.

It slows as it moves further away from the Sun

Meteors

A meteoroid is a small particle of debris in the Solar system. The visible path that enters the atmosphere is a meteor, commonly called a "shooting star" or "falling star". Many meteors are part of a meteor shower.
