Saturn’s moons are grouped based on their size, orbits, and proximity to Saturn. The innermost moons and regular moons all have small orbital inclinations and eccentricities and prograde orbits. Meanwhile, the irregular moons in the outermost regions have orbital radii of millions of kilometers, ...

So, what's the purpose of Mars' moons? While they don't cause massive tidal waves or anything elselike our Moon does on Earth, scientists have toyed with the idea of using Phobos as a base to observe Mars and launch robots/astronauts to the planet. It'll still be quite a few years...
(81 miles) long and are spaced roughly 35 kilometers (22 miles) apart. They were first observed in 2005 by NASA's unmanned Cassini spacecraft that has orbited Saturn and its moons since 2004. Cassini data have strongly indicated that the moon's plumes probably originate in a biomolecule-...
