Because of its detailed ring system, Saturn is known as the “jewel of the solar system.” Saturn’s rings stretch from edge-to-edge as wide as 175,000 miles, about the distance from the Earth to the Moon. Even though the other gas planets in our solar system have a series of rings, Saturn’s system of rings is the most prominent and well known. However, a new exoplanet–some 420 light years from Earth–has been discovered with a ring system that dwarfs any ring system ever before seen; it is a ring system over 200 times larger than the rings of Saturn.
