Astronomers since long have been baffled by the second largest planet of our solar system. But now a latest study claims the size of Saturn's outermost ring is far larger than previously thought.

The planets' radius and density has been discovered and has long been put into textbooks and reading materials to inform the people about facts associated with it.

The studies conducted on this particular topic included the dimensions and the size of its rings. However, although the facts about the rings have been already established, further studies showed that the previous known diameters are not accurate.

The study showed that the outermost ring of Saturn is one that is not clearly visible and appear to be dimmer on an astronomical scan.

The new findings presented in the study showed that this ring is approximately 7,000 times bigger than the planet it surrounds.

University of Maryland's, Douglas Hamilton, and co-researchers, saw images from NASA's WISE telescope and confirmed that 'Phoebe Ring' is indeed larger than Saturn and even exhibited small unidentified particles inside it. It vertical distance is approximately 1.5 million miles, they said.

The researchers said these unknown particles may be ice materials from a micro-meteoroid impact from the planet's moon, Phoebe.

The researchers in an explanation said to get a clearer and a bigger picture of how big the ring is, imagine that it starts to stretch about 3.7 million miles from the planet it orbits, and then expands to about 10 million miles away.

The latest study was published in the June 11 issue of the journal Nature.
