Most ring formation theories usually cite the ring as forming from the initial protoplanetery disk that didn’t get swept by the planet or expelled by it. read more

Thanks to exploration efforts mounted in the past few decades, which have seen space probes dispatched to the outer Solar System, we have come to understand that all the gas giants – Jupiter, Saturn, Uranus and Neptune – all have their own ring systems. read more
