Scientists from time to time made a forecast of the orbit of Phobos, the study showed that for every 100 years Mars attracts a satellite by 2 meters. According to scientists, in 20-40 million years the satellite will be destroyed by the tidal forces of Mars into many parts — this is of course approximate, but inevitable. The gravitational forces of Mars form a kind of ring around it, like Saturn, smaller, but it will be.
Eventually, the largest pieces of this ring will fall to the surface of Mars in millions of years. When falling and hitting Mars, quite large craters will be formed. When it comes to small pieces, they will also disappear over time. All this will look like periodic meteor showers. Meteor showers can be observed from the surface of the Red Planet.
