Astronomers have [prompted / promoted] Saturn as the planet with the most moons. Saturn has [overtaken / overtook] the solar system's largest planet Jupiter as the "king of the moons". The astronomers [recent / recently] discovered 20 new moons orbiting Saturn, which brings the planet's total [number / orbit] to 82. This edges out Jupiter, with 79 [celestial / celery] bodies, into second [place / part] . Each of the newly-discovered moons is at least 5km [in / on] diameter. Seventeen of them orbit Saturn backwards and take more than three years to [compete / complete] one orbit of Saturn. The astronomers found the moons using the powerful Subaru telescope, [locating / located] on Hawaii. The research team will now look for moons [that / what] are around a kilometer in diameter.

Lead astronomer Dr Scott Sheppard commented on the [perception / perceived] origins of the new moons. He said: "We don't think they [formed / framed] with the planet. We think they were [captured / captive] by the planet in the past." He [posited / posit] that Saturn sucked in a [sterling / swirling] mixture of gas and dust to form the moons. Dr Shepperd added: "We think these moons interacted with [these / that] gas and dust. These were comets or asteroids that [happened / occurred] to be passing by....They were captured into orbits around the planet [rather / instead] than falling into the planet. We think these are the last [remnants / rumors] of what formed Saturn." The moons will be named in a competition after [gigantic / giants] from Gallic, Inuit and Norse mythology.
