Phys.org / Neptune's tiny moons tell the story of Triton's destructive capture

Neptune's moon and ring system stand out among the giant planets because of the strange imbalance between its one very large moon and its many tiny moons. Its largest moon, Triton, makes up more than 99% of the mass of all ...
