How many planets have rings

The rings of Uranus are thought to be less than million years which makes them very young in planetary years. They formed from the remnants of colliding moons that existed around the planet. Only thirteen rings have been identified in the ring system although researchers believe there are more.

They are incredibly faint and opaque and are a few miles wide. The components of the ring are larger compared to the other ring systems. Some of the rings are made up of tiny dust particles and difficult to see using Earth-based telescopes. So far, only six rings have been observed, but astronomers describe them as faint and tenuous. The rings of Neptune are dark and made up of organic compounds. The first theory states that the rings formed at the same time as the planet.

Some particles of gas and dust that the planets are made of were too far away from the core of the planet and could not be squashed together by gravity. They remained behind to form the ring system. The second theory , and my personal favourite, is that the rings were formed when two of the moons of the planet, which had formed at the same time as the planet, somehow got disturbed in their orbits and eventually crashed into each other an orbit is the circular path that the moon travels on around the planet.

The stuff that was left behind in this huge smash could not come together again to form a new moon. Instead, it spread out into the ring systems we see today. What we do know is that the rings around the various planets are all slightly different from one another, but they all share some characteristics too. First, they are all much wider than they are thick. The rings of Saturn, for example, are about ,km wide stretching away from the planet but only metres thick.

The other thing that all rings systems share is that they are all made of small particles of ice and rock. The smallest of these particles are no bigger than dust grains, while the largest of the particles are about 20 metres in diameter — about the size of a school hall. Are moons always smaller than planets? How do the planets stay in orbit around the sun? How did the planets get their names?
