Solsystemet best\u00e5r av Solen og alle de mindre himmellegemene som kretser rundt den. Bortsett fra Solen er de \u00e5tte store planetene de st\u00f8rste himmellegemene i Solsystemet. N\u00e6rmest Solen ligger fire relativt sm\u00e5, steinplaneter \u2013 Merkur, Venus, Jorden og Mars.<\/p>\n<\/div>\n

Utenfor Mars ligger asteroidebeltet \u2013 et omr\u00e5de som best\u00e5r av millioner av steinete legemer. Disse er rester fra planetdannelsen for 4,5 milliarder \u00e5r siden.<\/p>\n

P\u00e5 den andre siden av asteroidebeltet ligger de fire gassgigantene \u2013 Jupiter, Saturn, Uranus og Neptun. Disse planetene er mye st\u00f8rre enn Jorden, men sv\u00e6rt lette i forhold til st\u00f8rrelsen. De best\u00e5r hovedsakelig av hydrogen og helium.<\/p>\n

Inntil nylig var den fjerneste kjente planeten en isverden kalt Pluto. Pluto er imidlertid mye mindre enn Jordens m\u00e5ne, og mange astronomer mener den er for liten til \u00e5 kunne kalles en ekte planet.<\/p>\n

Et objekt ved navn Eris, som er minst like stort som Pluto, ble oppdaget sv\u00e6rt langt fra Solen i 2005. De siste \u00e5rene har man oppdaget mer enn 1 000 isverdener som Eris utenfor Plutos bane. Disse kalles Kuiperbelt-objekter. I 2006 vedtok Den internasjonale astronomiske unionen at Pluto og Eris m\u00e5 klassifiseres som \u201cdvergplaneter\u201d.<\/p>\n

Enda lenger ute ligger kometene i Oort-skyen. Disse befinner seg s\u00e5 langt unna at de ikke kan ses selv med de st\u00f8rste teleskopene. Med jevne mellomrom blir en av disse kometene forstyrret og beveger seg mot Solen. Da blir den synlig p\u00e5 nattehimmelen.<\/p>","protected":false},"excerpt":{"rendered":"
