Scientists predict that Triton, one of _____'s moons, will eventually be torn apart by gravity and become a ring.

Explanation
Five rings and eight known moons surround Neptune. Triton, one of the planet's large moons, is the only large moon in our solar system that orbits its planet in the opposite direction. Scientists believe Triton, only slightly smaller than our planet's moon, may have been a comet that traveled around the Sun and was trapped by Neptune's gravitational pull. Scientists predict the moon will eventually be torn apart by gravity and become a ring. Nereid, another of the planet's moons, has the oddest shaped orbit of any moon in our solar system.
