0 Saturn holds the record for moons: more than 270 are known, most of them small lumps, and new ones are still being found. 2 Imagine a rainy day at minus 180 degrees: on Titan the rain is natural gas falling as liquid, filling lakes you could sail a boat on. 3 Little Enceladus is like a garden sprinkler made of ice: jets of water burst from cracks at its south pole, from an ocean hidden underneath, and the spray feeds one of Saturn's rings. 4 Other moons are odd too: Mimas looks like the Death Star, Iapetus is half black and half white, Hyperion is a tumbling sponge, and tiny shepherd moons herd the ice of the rings. 5 Saturn has the most known moons of any planet, more than 270, and the count is still rising. 6 Titan is Saturn's biggest moon, larger than the planet Mercury. 7 Titan is the only moon with a thick atmosphere. 8 Titan has rivers, lakes and seas, but they are filled with liquid methane and ethane, not water. 9 In 2005 the European Huygens probe parachuted onto Titan, the most distant landing ever made. 10 NASA's Dragonfly is a nuclear-powered drone helicopter due to launch in 2028 and fly between sites on Titan in the 2030s. 11 Saturn's small moon Enceladus sprays jets of water ice from cracks near its south pole, from a hidden ocean below. 14 Iapetus has one side as dark as coal and the other as bright as snow, and a strange ridge round its equator. 15 Hyperion is a lumpy moon like a sponge, full of deep craters, and it tumbles chaotically, in a messy, unpredictable way, as it orbits. 16 Small moons such as Prometheus and Pandora shepherd the narrow F ring, keeping its ice in a thin, sharp-edged band as sheepdogs keep sheep together. 17 The tiny moons Pan and Daphnis orbit inside gaps in Saturn's main rings. ← previous Saturn and its ringsnext → Uranus and Neptune↑ back to Space This page in Markdown → https://md.mova.elamur.ai/free/en/corpora/school/space/13-saturns-moons/
