DUBBED the "Jewel of the Solar System", Saturn with its beautiful rings is truly a glorious sight to behold. Made up of ice, dust and floating rock, the rings are actually a debris field that has been gravitationally locked to orbit Saturn. It is however, not the only planet to have rings, all of the gas giants boasts rings in one way or another and it's even predicted that Mars will eventually get its own set of rings in about a million years when its moon Phobos eventually disintegrates in its atmosphere. Some say the Earth used to have its own rings, is this true?
