Comet is the correct answer.
Comets are icy bodies from the Kuiper Belt and Oort Cloud which enter the inner solar system.
70% to 80% of a comet is made up of gas and water. 20% to 30% of a comet is chunks of metal and rocky material.
Short-period comets originate in the Kuiper belt, while Longer-period comets are originated in the Oort clouds.
FUN FACT: When a comet approaches the sun its tail is following, and when it moves away from the sun its tail is leading the comet.
