Mars’s Moon Phobos Might Be Destroyed Sooner Than Previously Thought

Summary: Did you know Mars is going to get beautiful rings just like Saturn? Mars has a tiny, potato-shaped moon named Phobos that orbits very close to the planet. Scientists used to think Phobos was a solid rock, but new research shows it might just be a giant pile of rubble held together by gravity. Because it is so fragile, Mars's strong gravity will tear it apart much sooner than we thought—in about 94 million years! When it breaks, all those pieces will spread out and form a stunning ring around the Red Planet.
