Mars may one day have its own ring system

Phobos, one of the two small moons of Mars, could eventually break apart and encircle the planet.
Saturn's spectacular rings have long made it one of the wonders of the solar system, but there is another planet that, in the distant future, might get the chance to inherit a ring system of its own.

The key lies in Phobos - one of the moons of Mars. Unlike our own moon which is 238,900 miles from the Earth, Phobos orbits only 3,700 miles above Mars and is getting closer all the time.

In somewhere around 20 to 40 million years it will get so close that the gravitational stress will literally tear Phobos apart - producing enough dust and debris to encircle the planet.

"Compared to Saturn's rings, we expect a future Martian ring to be much smaller and contain much less material," said geologist and study co-author Benjamin Black.

"But because that material will be spread over a smaller ring area, we predict that the initial density of a ring formed from the breakup of Phobos could rival or exceed the density of Saturn's rings."

Off the subject a little bit but I sometimes wonder if our civilization would be in any way different if Saturn were much closer to the earth and we would behold the beauty of its rings and wonder in times past about any spiritual connotation or whatever.

I would like to believe that we will view awe of the rings of Mars from the surface of Mars; that we as a civilization made a 21st century commitment to establish a new world on Mars.

If Saturn was to close, it's gravity would have a marked affect on Earth's revolution I'd think.

This is cool, I also saw on a tv show that one of Mars moons will hit the planet in a thousand years or so

If Saturn was to close, it's gravity would have a marked affect on Earth's revolution I'd think. That applies no matter what it might be that is "too close." The orbit would also be changed .It ain't gonna happen for at least a few million years, and the chances are overwhelming that you can add several more zeros to that estimate.

Well, sure. My point was that if it had happened while we were still developing, good chance that the change in orbit would be disasterous, not wonderous.
