    Some of the outer moons of Jupiter that gravitationally captured asteroids. If they gain enough angular momentum, they can escape and orbit The Sun instead of Jupiter.

    Phobos' orbit is prograde, but it orbits Mars so fast it seems to retrograde ON MARS by rising in the west and setting in the east because of Mars slower rotation rate. Phobos is moving closer to Mars. Eventually the gravitational stresses and strains will tear

    Phobos apart and create a ring at the Roche limit. https://en.m.wikipedia.org/wiki/Apparent_retrograd...
