Interesting fact:

Four planets in our solar system have a ring of some sort. Scientists believe that Mars too will have a ring in 20-40 million years when its moon Phobos is torn apart by the red planet's gravitational force. The ring would then be a fixture of Mars' planetary makeup for another 100 million years.
