The new moons bring Saturn's count to 46
Astronomers have discovered 12 new moons orbiting Saturn, bringing its number of natural satellites to 46.
The moons are small, irregular bodies - probably only about 3-7km in size - that are far from Saturn and take about two years to complete one orbit.
All but one circles Saturn in the opposite direction to its larger moons - a characteristic of captured bodies.
Jupiter is the planet with the most moons, 63 at the last count. Saturn now has 46. Uranus has 27 and Neptune 13.
