Bortom asteroidb\u00e4ltet ligger Jupiter, den femte planeten r\u00e4knat fr\u00e5n Solen. Allt med Jupiter \u00e4r stort. Den \u00e4r s\u00e5 stor att den l\u00e4tt skulle kunna sv\u00e4lja alla de andra planeterna (eller mer \u00e4n 1 300 jordklot). Den v\u00e4ger ocks\u00e5 mer \u00e4n dubbelt s\u00e5 mycket som alla de andra planeterna tillsammans. Trots sin enorma storlek \u00e4r Jupiter den planet som roterar snabbast, med ett varv p\u00e5 mindre \u00e4n 10 timmar.<\/p>\n<\/div>\n

Jupiter ligger fem g\u00e5nger s\u00e5 l\u00e5ngt fr\u00e5n Solen som Jorden, vilket g\u00f6r att dess yttemperatur \u00e4r l\u00e5g, omkring \u2013145 \u00b0C. Ungef\u00e4r var 13:e m\u00e5nad n\u00e4rmar den sig oss och lyser d\u00e5 mycket starkt p\u00e5 natthimlen.<\/p>\n

Jupiter \u00e4r en gigantisk gasklot utan fast yta. Den best\u00e5r huvudsakligen av de mycket l\u00e4tta gaserna v\u00e4te och helium. Genom teleskop ser man en molnig atmosf\u00e4r med f\u00e4rgglada b\u00e4lten och fl\u00e4ckar. Det st\u00f6rsta inslaget \u2013 kallat den stora r\u00f6da fl\u00e4cken \u2013 \u00e4r en gigantisk storm som \u00e4r flera g\u00e5nger st\u00f6rre \u00e4n jorden. Den har rasat oavbrutet i mer \u00e4n 300 \u00e5r.<\/p>\n

Jupiter har en svag dammring, \u00f6ver 100 000 km bred, som uppt\u00e4cktes av rymdsonden Voyager. Den omkretsas dessutom av den st\u00f6rsta familjen av m\u00e5nar (63 enligt den senaste r\u00e4kningen).<\/p>\n

Fyra av dessa, som uppt\u00e4cktes av den italienske vetenskapsmannen Galileo \u00e5r 1610, \u00e4r mycket stora. Io har hundratals vulkaner som t\u00e4cker dess yta med gulorange svavel. Europa har en sl\u00e4t, isig yta som ser ut som ett sprucket \u00e4ggskal. Ganymedes har ljusa och m\u00f6rka fl\u00e4ckar med r\u00e4fflor och kratrar. Callisto har en ur\u00e5ldrig, kraterrik yta.<\/p>","protected":false},"excerpt":{"rendered":"
