Saturn is now the planet with the most moons. It has overtaken Jupiter as "king of the moons". Astronomers found 20 new moons orbiting Saturn, which now has 82 moons. Jupiter has 79. Each of the newly-discovered moons is at least 5km in diameter. Seventeen of them orbit Saturn backwards. They take three years to complete one orbit of Saturn. The astronomers will now look for moons that are a kilometer in diameter.
An astronomer spoke about the origins of the moons. He said: "We don't think they formed with the planet. We think they were captured by the planet in the past." He thinks Saturn sucked in a mixture of gas and dust to form the moons. He added: "We think these are the last remnants of what formed Saturn." The moons will be named in a competition after giants from Gallic, Inuit and Norse mythology.
