Asteroidivy\u00f6hykkeen takana sijaitsee Jupiter, viides planeetta Auringosta laskien. Jupiterissa kaikki on suurta. Se on niin suuri, ett\u00e4 se voisi helposti nielaista kaikki muut planeetat (tai yli 1 300 Maata). Se painaa my\u00f6s yli kaksi kertaa enemm\u00e4n kuin kaikki muut planeetat yhteens\u00e4. Valtavasta koostaan huolimatta Jupiter on nopeimmin py\u00f6riv\u00e4 planeetta: se tekee yhden kierroksen alle 10 tunnissa.<\/p>\n<\/div>\n

Jupiter on viisi kertaa niin kaukana Auringosta kuin Maa, joten sen pintal\u00e4mp\u00f6tila on alhainen, noin \u2013145 \u00b0C. Noin 13 kuukauden v\u00e4lein se l\u00e4hestyy meit\u00e4 ja n\u00e4kyy eritt\u00e4in kirkkaana y\u00f6taivaalla.<\/p>\n

Jupiter on valtava kaasupallo, jolla ei ole kiinte\u00e4\u00e4 pintaa. Se koostuu p\u00e4\u00e4asiassa eritt\u00e4in kevyist\u00e4 kaasuista, vedyst\u00e4 ja heliumista. Kaukoputkien avulla n\u00e4kyy pilvinen ilmakeh\u00e4, jossa on v\u00e4rikk\u00e4it\u00e4 vy\u00f6hykkeit\u00e4 ja t\u00e4pli\u00e4. Suurin piirre \u2013 jota kutsutaan Suureksi punaiseksi t\u00e4pl\u00e4ksi \u2013 on j\u00e4ttim\u00e4inen myrsky, joka on useita kertoja Maata suurempi. Se on py\u00f6rinyt taukoamatta jo yli 300 vuotta.<\/p>\n

Jupiterilla on himme\u00e4, yli 100 000 km leve\u00e4 p\u00f6lyrengas, jonka Voyager-avaruusluotain l\u00f6ysi. Sen kiertoradalla on my\u00f6s suurin kuperhe (viimeisimm\u00e4n laskennan mukaan 63 kuuta).<\/p>\n

Nelj\u00e4 n\u00e4ist\u00e4, jotka italialainen tiedemies Galileo l\u00f6ysi vuonna 1610, ovat eritt\u00e4in suuria. Io:n pinnalla on satoja tulivuoria, jotka peitt\u00e4v\u00e4t sen kelta-oranssilla rikkipinnalla. Europan pinta on sile\u00e4 ja j\u00e4inen, ja se n\u00e4ytt\u00e4\u00e4 halkeillulta munankuorelta. Ganymedella on vaaleita ja tummia alueita, joissa on uria ja kraattereita. Callistolla on ikivanha, kraatterinen pinta.<\/p>","protected":false},"excerpt":{"rendered":"
