New image shows Saturn’s moon dwarfed by planet’s rings

A recent photo taken by the Cassini spacecraft shows the enormity of Saturn’s rings as compared to its icy moon, Mimas.

But while it appears that the rings are far more massive than Mimas, scientists believe that the mass levels may not be far off.  According to NASA, the rings, which are made of small, icy particles are very thin contain only a small amount of actual material.

The Cassini mission is expected to determine the mass of Saturn's rings as the mission winds down by tracking radio signals from the spacecraft as it flies close to the rings.
