Saturn's Massive Ring
NASA's Spitzer Space Telescope discovered the massive ring around Saturn - by far the planet's largest.
The particles in the new ring occupy a vast region in space, with the ring starting 3.7 million miles away from the planet, and extending to 7.4 million miles. The vertical height is 20 times the diameter of the planet.
You would have to line up 300 Saturns in a row to match the ring's diameter.
