- Mars will tear its own moon apart. Now scientists think it could be . . .
Moon Phobos is spiralling towards Mars, meaning it could one day disintegrate and form rings around the Red Planet Unravelling of a rubble moon They found that if Phobos does indeed have a relatively low cohesion, its surface material will start being ripped away long before it approaches the Roche limit of around 1 6 times the radius of Mars

Mars’s moon Phobos, once thought to face a slow and steady demise due to tidal forces, could actually break apart much sooner and in a far more dramatic way New research suggests that its destruction might involve violent eruptions of material, obliterating the moon long before it reaches the Roche limit
