Io waxay door muhiim ah ka ciyaartaa qaabeynta aagga birlabta ee Jupiter, waxay u dhaqmaysaa sida koronto-dhaliye oo horumarin kara 400,000 volts oo dhankeeda ah waxayna abuuri kartaa koronto koronto ah 3 milyan oo amperes, waxay sii deyneysaa ions oo siinaya Jupiter aagga birlabta oo la buufiyay wax ka badan laba jeer cabirkii ay lahaan lahayd. Magnetosphere-ka Jupiter wuxuu ka soo saaraa gaasaska iyo boodhka jawiga khafiifka ah ee Io ee heerka 1 tan ilbidhiqsi kasta. Maaddadani waxay badanaa ka kooban tahay ionised iyo atomic sulfur, oxygen iyo chlorine; sodium atomic iyo potassium; molecular sulfur dioxide iyo sulfur; iyo boodhka sodium chloride. Maaddadaani waxay ka soo jeedaan dhaqdhaqaaqa Io ee volcanic, laakiin maaddada ka baxsan aagga birlabta ee Jupiter iyo u gudubka interplanetary waxay si toos ah uga timaaddaa jawiga Jupiter.
