Answer:
The correct answer is "a comet".
Step-by-step explanation:
A loose, icy body with a long, narrow orbit is a comet. A comet is made of ice, that is the reason why most comets start to release their gasses in a process known as outgassing when they pass close to the Sun. Comets have a long, narrow orbit that most of time follows an elliptical path respect to the Sun, which allows that most of the comets do not get close to the Earth.
