Most people are aware that there are many rings of Saturn that are separated by gaps such as the Cassini division. These rings and gaps are caused by ‘gravitational resonance’ between Saturn and many of its moons which can each be responsible for a ring. This same principle is in effect between the Sun and the planet Jupiter which causes the same kinds of ‘rings’ and ‘gaps’ that occur in the asteroid belt between Mars and Jupiter.
