Saturnus on kuudes planeetta Auringosta laskien. Sit\u00e4 pidettiin kaukaisimpana planeettana, kunnes kaukoputki keksittiin.<\/p>\n<\/div>\n

Saturnus on kooltaan toiseksi suurin Jupiterin j\u00e4lkeen, ja se koostuu p\u00e4\u00e4asiassa kevyist\u00e4 kaasuista, vedyst\u00e4 ja heliumista. Saturnuksen sis\u00e4\u00e4n mahtuisi 764 Maata, mutta t\u00e4m\u00e4 kaasuj\u00e4ttil\u00e4inen painaa vain 95 kertaa niin paljon kuin kivinen planeettamme. Jos kaikki planeetat voitaisiin laittaa vesialtaaseen, Saturnus olisi ainoa, joka pysyisi pinnalla.<\/p>\n

Kokostaan huolimatta Saturnus py\u00f6rii kerran hieman yli 10 tunnissa. Sen py\u00f6rimisnopeus on niin suuri, ett\u00e4 se pullistuu ulosp\u00e4in p\u00e4iv\u00e4ntasaajalla, mink\u00e4 vuoksi se n\u00e4ytt\u00e4\u00e4 litistyneelt\u00e4 pallolta.<\/p>\n

Kaukoputkessa Saturnus n\u00e4ytt\u00e4\u00e4 vaaleankeltaiselta. Sill\u00e4 ei ole kiinte\u00e4\u00e4 pintaa, joten n\u00e4emme pilvi\u00e4, jotka n\u00e4kyv\u00e4t vaaleina ja tummina raidoina. N\u00e4m\u00e4 pilvet liikkuvat eritt\u00e4in voimakkaiden tuulien mukana. Suuri osa n\u00e4it\u00e4 tuulia aiheuttavasta l\u00e4mm\u00f6st\u00e4 tulee planeetan sis\u00e4lt\u00e4. Pilvien yl\u00e4puolella on tasainen, kiekkomainen rengasj\u00e4rjestelm\u00e4.<\/p>\n

Suuri osa siit\u00e4, mit\u00e4 tied\u00e4mme Saturnuksesta, on per\u00e4isin NASA:n ja ESA:n Cassini-Huygens-luotainohjelmasta. Cassini-luotain on kiert\u00e4nyt planeetan kiertoradalla 1. hein\u00e4kuuta 2004 l\u00e4htien. Se on tutkinut monia Saturnuksen kuita, erityisesti planeetan kokoista Titania. Se on my\u00f6s l\u00e4hett\u00e4nyt takaisin eritt\u00e4in yksityiskohtaisia kuvia ja muuta tietoa Saturnuksen ukkosmyrskyist\u00e4, tuhansista j\u00e4isist\u00e4 renkaista ja magneettikent\u00e4st\u00e4.<\/p>\n

14. tammikuuta 2005 Europen Huygens-luotain laskeutui laskuvarjolla Titanin piilotetulle pinnalle. Se oli ensimm\u00e4inen pehme\u00e4 laskeutuminen toisen planeetan kuuhun (omaa Kuutamme lukuun ottamatta). Oranssi Titan osoittautui omituiseksi, j\u00e4iseksi maailmaksi, jossa metaanisade t\u00e4ytt\u00e4\u00e4 j\u00e4rvet ja joet.<\/p>","protected":false},"excerpt":{"rendered":"
